Terrestrial Planet Formation in Binary Star Systems

first_imgThe answer, of course, is that it depends on the system. In principle, stable orbits should be possible for planets that are always much closer to one star than the other. But the devil is in the details — if scientists are going to spend valuable telescope time on binary stars, they need to know what they’re looking for. How close can two stars be to each other and still form planets? And even if planets form, can their orbits remain stable over billions of years? A small collaboration of scientists at NASA’s Ames Research Center (Elisa Quintana, Jack Lissauer), University of Michigan (Fred Adams), and the Carnegie Institution of Washington (John Chambers) has taken steps to answer these questions. Modern telescopes can measure the orbital parameters of binary stars quite accurately, so it makes sense to first ask what kinds of star systems will preserve the innermost region of the protoplanetary disk. The simulations of Quintana and her colleagues are fairly straightforward. After choosing the masses and orbital parameters of the two stars, 140 planetesimals (mass = 1% Mearth) and planetary embryos (mass = 10% Mearth) are arranged around one of the stars so that their overall mass distribution resembles that of a protoplanetary disk. “The disk is modeled after the Solar nebula,” Quintana explains, “we’re comparing the planet formation process in these binaries to models of the Solar System.” In other words, they are trying to find out what our Solar system might have looked like if the Sun were a binary star.The simulation calculates the force of gravity between every pair of objects and adjusts their positions accordingly at one-week intervals. When two objects collide, if their speeds are not too high, they stick together into a body of greater mass. Eventually, the system forms a handful of stable, massive planets similar to the inner solar system.”Each simulation takes approximately 3 – 4 weeks.” Quintana tells PhysOrg.com. “This corresponds to 100 – 200 million years of simulated time.” Dr. Quintana goes on the explain that this is actually rather short, because many planetesimals are thrown out of the disk or into the central star as the simulation progresses. “The same disk of 154 bodies around the Sun, without any giant planets or a stellar companion [to eject particles], takes twice as long.” To explore a wide variety of possible binary star systems and obtain statistically significant results, Quintana and her colleagues performed over a hundred of these simulations — that’s several years of computer time! All of their simulations form at least one planet, an encouraging result. It turns out that the most important factor is the companion star’s periastron, or point of closest approach to the star with the disk. A companion that gets as close as the orbit of Saturn (about 10 times farther than the Earth from the Sun) removes very little material from the inner disk, and even speeds up the process of planet formation by nudging the planetesimals into different orbits from time to time. A companion star that gets as close as Jupiter (about 5 times farther than the Earth from the Sun), however, will limit planet formation to the hottest central regions.“Over half of the binaries [in astronomical surveys] are wide enough to allow planet formation in the habitable zone of solar-type stars.” Quintana concludes. That fraction expands the catalogue of interesting stars significantly, but many possibilities remain unexplored.For example, it is entirely possible for compact binary systems to share a protoplanetary disk; the planetesimals would just orbit both stars at once. And there is no reason for just one of the stars to have planets! Another open question in whether icy planetesimals, which normally form beyond 5 AU, can still reach the inner disk to deliver water to the rocky worlds. “It is more difficult,” Quintana admits, “but there are many scenarios for having habitable planets in binary star systems.” Most of the disk is not treated in these simulations, and there could be plenty of room around or between the two stars for comets and even gas giants to form. The water will probably still be available, but it is too soon to estimate how much of it might reach these worlds.Physical simulations of planet formation have the potential to answer these questions and more. By the time Kepler and CoRoT start detecting Earth-like worlds, this line of research should have given us a good idea what to expect.Citation: “Terrestrial Planet Formation Around Individual Stars Within Binary Star Systems” by Elisa Quintana, Fred Adams, Jack Lissauer, and John Chambers, Astrophysical Journal (in press) 2007.

The horizontal axis gives the radius of its orbit in astronomical units (AU; the Earth’s distance from the Sun), and the vertical axis gives the eccentricity of the orbit (zero is a perfect circle). The filled green circles represent our own rocky planets: Mercury, Venus, Earth, and Mars. The grey band indicates the solar system´s habitable zone. The lower plot shows planets from simulations where the point of closest approach between the stars is 10 AU (approximately equal to Saturn’s distance from the Sun). The inner disk has not been compromised; many planets form in and around the habitable zone. In the upper plot the companion star cuts this distance in half, and planet formation in the habitable zone is no longer likely. Scientific interest in the physics of planet formation is at an all-time high. Astronomers and physicists have reached a consensus on the underlying theory, or at least its outlines. A star is born from an immense cloud of gas and dust, which slowly contracts and heats up through the action of gravity. Some of the cloud falls towards the center, where it collects into a hot, dense ball of gas that will eventually become the star. The rest of the cloud orbits the center, contracting and flattening into a protoplanetary disk. Tiny grains of rock and ice stick to each other as they orbit within the disk, eventually growing into ‘planetesimals’ — small lumps of rock and ice similar to asteroids and comets. At this point gravity speeds up the process of planet formation considerably. Rocky planets form close to the newborn star, where the radiant heat prevents ice from forming. Icy planets form in the cold outer regions, but are much larger to begin with and quickly transform into gas giants. This document is subject to copyright.

The list of confirmed extrasolar planets keeps growing, and has now passed two hundred members — almost all of which are gas giants like Jupiter and Saturn. But the hunt is on for Earth-like worlds! With the successful launch of France’s CoRoT satellite (December 27, 2006) and the promise of NASA’s Kepler mission (due to be launched October 2008), the next five years should see the detection of numerous terrestrial planets around distant stars. But which stars should these telescopes be pointed at? Recent research has shown that these planets are probably quite common, and can even form in binary star systems.

The method of choice is numerical simulations, which can follow the evolution of a disk by modeling its gas dynamics (in the early stages of planet formation) or the gravitational interactions between planetesimals (in the later stages). Such research has shown that planets should almost always form, at least around an isolated star like our Sun.Of course, star formation is a more complicated business.Stars rarely, if ever, form in isolation. More often, a giant molecular cloud will create dozens or hundreds of stars in relatively close proximity. Binary star systems, composed of two stars orbiting their mutual center of gravity, are actually just as common as singles. For stars the size of our Sun, about 50% form in binary systems.In the search for other worlds like our own, should we limit ourselves to stars like our own? Must we cut the field in half before we start looking? Might binary stars harbor Earth-like planets as well? last_img read more

The doughy blob moves by inflating and deflating – a new technique its developers call “jamming.” As the researchers explain in the video below, the jamming mechanism enables the robot to transition from a liquid-like to a solid-like state. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. As a new kind of chemical robot (or chembot), the blob bot has stretchy silicone skin, which is composed of multiple cellular compartments that each contain a “jammable slurry.” When some of these cells are unjammed, and an actuator in the center of the robot is inflated, the robot inflates in the areas of the unjammed cells. By controlling which cells are unjammed, the researchers can change the shape of the robot and make it roll in a specific direction.The new robot is being funded by DARPA, which gave iRobot $3.3 million to work on the chembot last year. The goal is to build a robot that can squeeze through tiny openings smaller than its own dimensions, which could be valuable in a variety of missions. The video shows the robot from about one year ago, and since then the researchers have been working on adding sensors and connecting multiple blob bots together. • Join PhysOrg.com on Facebook!• Follow PhysOrg.com on Twitter!via: IEEE Spectrum© 2009 PhysOrg.com Two Robot Chefs Make Omeletscenter_img Explore further The blob bot uses a jamming mechanism to change its shape and roll, enabling it to squeeze into small spaces.

Jumping spiders that love smelly socks could help fight malaria

first_img Mosquitoes supply spider with blood Citation: Jumping spiders that love smelly socks could help fight malaria (2011, February 17) retrieved 18 August 2019 from https://phys.org/news/2011-02-spiders-smelly-socks-malaria.html Explore further The spider (Evarcha culicivora), which is also known as the vampire spider, is a native of East Africa and is known to go into a kind of feeding frenzy when it smells blood, killing up to 20 female blood-filled Anopheles mosquitoes (the type that carry malaria) in a single session, but not necessarily eating them all immediately.Dr Fiona Cross and Professor Robert Jackson of the University of Canterbury in New Zealand thought the jumping spider could be a useful tool in the fight against malaria if people were encouraged to have them living in their homes, and even before carrying out their research suspected the spiders might be attracted to human odors because they are commonly found in tall grass next to human dwellings.Cross and Jackon devised an “olfactometer” to test their suspicions. They placed each spider into a small holding chamber connected to an exit chamber and pumped air into the holding chamber from one of two boxes. One of the boxes contained a clean sock, and the other contained a smelly sock that had been worn for 12 hours. The spider was free to move into the exit chamber at any time, and this chamber had normal, unscented air.The results of the experiment were that the spiders stayed in the holding chamber 15 to 30 minutes longer if their air was laden with the scent of smelly socks than if the air carried the clean sock smell. The behavior was seen in all 109 spiders tested, regardless of their age or gender.Dr Cross said the discovery ties in with some of the spider’s behavior patterns, and it is the first time a spider’s attraction to human odors has been demonstrated. She said since the spider lives in areas where malaria is rife it makes sense to learn as much as possible about it, especially ways in which people can lure the spiders into living in their houses without attracting more mosquitoes at the same time. She said the spider will never be “the magic bullet” that wipes out malaria, but it could be helpful and it is freely available in the environment.In 2003 Professor Jackson discovered the spider and showed that it preys on mosquitoes responsible for malaria, especially females engorged after a blood meal. He also showed the spiders can recognize the mosquitoes both from their appearance and their smell, which was unexpected in a jumping spider known more for its excellent eyesight. Jackson then teamed with Cross and in 2009 they showed the spider becomes irresistible to the opposite sex when they have eaten a meal of blood-filled spiders.The paper is published in the journal Biology Letters.

New accreting millisecond Xray pulsar discovered

Green symbols, blue diamond and red hexagon represent the observations collected by XMM-Newton, NuSTAR and INTEGRAL respectively. Credit: Sanna et al., 2016. More information: Discovery of a new accreting millisecond X-ray pulsar in the globular cluster NGC 2808, arXiv:1611.02995 [astro-ph.HE] arxiv.org/abs/1611.02995AbstractWe report on the discovery of coherent pulsations at a period of 2.9 ms from the X-ray transient MAXI J0911-655 in the globular cluster NGC 2808. We observed X-ray pulsations at a frequency of ∼339.97 Hz in three different observations of the source performed with XMM-Newton and NuSTAR during the source outburst. This newly discovered accreting millisecond pulsar is part of an ultra-compact binary system characterised by an orbital period of 44.3 minutes and a projected semi-major axis of ∼17.6 lt-ms. Based on the mass function we estimate a minimum companion mass of 0.024 M⊙, which assumes a neutron star mass of 1.4 M⊙ and a maximum inclination angle of 75∘ (derived from the lack of eclipses and dips in the light-curve of the source). We find that the companion star’s Roche-Lobe could either be filled by a hot (5×106 K) pure helium white dwarf with a 0.028 M⊙ mass (implying i≃58∘) or an old (>5 Gyr) brown dwarf with metallicity abundances between solar/sub-solar and mass ranging in the interval 0.065−0.085 M⊙ (16 < i < 21). During the outburst the broad-band energy spectra are well described by a superposition of a weak black-body component (kT∼ 0.5 keV) and a hard cutoff power-law with photon index Γ∼ 1.7 and cut-off at a temperature kTe∼ 130 keV. Up to the latest Swift-XRT observation performed on 2016 July 19 the source has been observed in outburst for almost 150 days, which makes MAXI J0911-655 the second accreting millisecond X-ray pulsar with outburst duration longer than 100 days. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. X-ray pulsars exhibit strict periodic variations in X-ray intensity, which can be as short as a fraction of a second. AMXP are a peculiar type of X-ray pulsar in which short spin periods are caused by long-lasting mass transfer from a low-mass companion star through an accretion disc onto a slow-rotating neutron star. They are perceived by the scientific community as astrophysical laboratories that could be essential to our understanding of thermonuclear burst processes.MAXI J0911-655 was first spotted on Feb. 19, 2016, by the Monitor of All-sky X-ray Image (MAXI) nova-alert system, mounted on the International Space Station. MAXI searches for transient objects using its real-time Gas Slit Camera (GSC). It found the source at a position compatible with the globular cluster NGC 2808.A few days later, the Burst Alert Telescope (BAT) aboard NASA's Swift space telescope detected X-ray activity from MAXI J0911-655, confirming that it is an X-ray transient source. Follow-up observations of this source during outburst, conducted by a team of European researchers led by Andrea Sanna of the University of Cagliari in Italy, uncovered coherent pulsations from this X-ray transient."Here, we report on the discovery of coherent ms X-ray pulsation from MAXI J0911-655, and we describe the detailed analysis of XMM-Newton and NuSTAR observations from which we derived the orbital solution for the pulsar," the scientists wrote in the paper.Using ESA's XMM-Newton space observatory and NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), the team detected X-ray pulsations at 339.97 Hz during the outburst of the new X-ray source, with an average pulse fraction of 7 percent. This observational campaign was carried out in April and May 2016 and allowed the researchers to calculate that these pulsations have a period of 2.9 milliseconds. The researchers also found that MAXI J0911-655 is part of an ultra-compact binary system with an orbital period of about 44 minutes and a projected semi-major axis of approximately 17.6 lt-ms. They calculated that the neutron star is about 40 percent more massive than the sun and that the companion star has a minimum mass of about 0.024 solar masses.However, the most intriguing thing about the newly discovered pulsar is that it is a rare example of an accreting, rapidly-rotating neutron star harbored in a low-mass X-ray binary system. So far, only 18 such AMXPs have been detected and almost 80 percent of them show persistent X-ray pulsation during the outburst phase. Therefore, any new addition to this list is of high scientific value for astronomers trying to better understand outburst processes.Moreover, MAXI J0911-655 turns out to be the second AMXP with an outburst duration longer than 100 days. The researchers noted that if the outburst started with the first detection of the source, it indicates that the outburst lasted at least 150 days, which is quite long when compared with other AMXPs. (Phys.org)—A new accreting millisecond X-ray pulsar (AMXP) has been found in one of our galaxy's most massive clusters, NGC 2808. The newly detected AMXP received designation MAXI J0911-655 and is part of an ultra-compact binary system. A paper describing the discovery was published Nov. 9 on the arXiv pre-print server.

Stars as random number generators could test foundations of physics

first_img Physicists demonstrate new way to violate local causality (Phys.org)—Stars, quasars, and other celestial objects generate photons in a random way, and now scientists have taken advantage of this randomness to generate random numbers at rates of more than one million numbers per second. Generating random numbers at very high rates has a variety of applications, such as in cryptography and computer simulations. Explore further © 2017 Phys.org Citation: Stars as random number generators could test foundations of physics (2017, May 16) retrieved 18 August 2019 from https://phys.org/news/2017-05-stars-random-foundations-physics.html This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. However, Bell tests have several loopholes. Typically, loopholes are ways for the objects being measured to secretly share information in a classical way in order to make it appear that local realism is violated when it is not. Although physicists have recently closed two of these loopholes (the locality loophole and detection loophole), there may always be some loopholes that can conceivably circumvent the restrictions of the test. One such possibility is called the freedom-of-choice (or randomness) loophole. This loophole suggests that the detector settings—which are determined using random number generators—could have somehow been correlated even before the experiment began. Before now, it has been thought that these correlations could have occurred just a fraction of a second before the start of the experiment.By using random number generators based on cosmic sources, the researchers showed that these correlations must have occurred before the photons left the stars, which is at least 3000 or so years before the experiment began—an improvement of more than 16 orders of magnitude. (A couple months ago, a paper was independently published that restricted the correlations to at least 600 years in the past, using similar methods based on cosmic sources of random number generation.)In addition, a third independent group of researchers has recently suggested that the time constraint for the freedom-of-choice loophole could be pushed back by billions of years by using very distant quasars as random number generators. To further pursue this possibility, the researchers in the new study suggest that a satellite-based cosmic Bell experiment may achieve better results than Earth-based experiments because, for one thing, it would avoid atmospheric disturbances. They hope to further pursue such improvements in the future. But the researchers in the new study are also interested in using these cosmic random number generators for another purpose: to test the foundations of physics by progressively addressing another loophole in the Bell tests. While Bell tests show that quantum particles are correlated in ways that cannot be explained by classical physics, the results may not be reliable if parts of these tests manage to take advantage of any kind of loophole. The researchers, led by Jian-Wei Pan, at the University of Science and Technology of China in Shanghai, have published a paper on using cosmic sources to generate random numbers in a recent issue of Physical Review Letters.”We presented an experimental realization of cosmic random number generators (RNGs) and a realistic design of an event-ready Bell test experiment with these RNGs to address the freedom-of-choice loophole while closing the locality and efficiency loopholes simultaneously,” coauthor Jingyun Fan told Phys.org. “It will be of high interest to implement the proposed experiment in the near future.”In their work, the researchers used an optical telescope located at the Astronomy Observatory in Xinglong, China, to collect light from a variety of very bright and distant cosmic radiation sources. Some of these objects are more than a trillion times brighter than our Sun and located hundreds of millions of light-years away.Since the time interval between photon emission events is random, the photons are detected by the telescope at random time intervals. The device has a time resolution of 25 picoseconds (a picosecond is one trillionth of a second). On average, a photon is detected about once every 100 nanoseconds, corresponding to more than a million photons detected per second. This rate is competitive with today’s current best random number generators, which use lasers as the photon source. In the second part of their study, the physicists proposed that this cosmic random number generator could be used to improve Bell tests. These tests aim to show that, unlike our observations of the classical world, the quantum world does not obey local realism—a concept that refers to a combination of locality (that objects cannot influence each other across large distances) and realism (that objects exist even before any measurement is made). Violating a Bell inequality shows that, at the quantum level, nature violates either locality or realism, or both.

What to Do When the Boss Is Wrong

first_img— In better-run offices, employees defy their superiors overtly. Back in the early 1980s, when Joanna Hoffman was in charge of marketing for Apple’s nascent Macintosh computer system, her boss, Steve Jobs, was a demanding, tantrum-throwing perfectionist. According to his biographer, Walter Isaacson, every year from 1981 on, the team developing the Mac gave an award to the person who could best stand up to Jobs. The first winner was Hoffman. Mercurial bosses in dysfunctional offices sometimes give orders that their employees just ignore—even when that dysfunctional office is the highest in the country. According to Robert Mueller’s recent report, Donald Trump tried to get his staff to impede the special counsel’s investigation, but figures such as Don McGahn and Rod Rosenstein protected the president—and themselves—by quietly letting those orders slide. Workplaces function better, business ethicists point out, when they make room for a certain amount of defiance. “I think you always have to make independent judgments about orders that come down to you,” Charlan Nemeth, a psychology professor at the University of California at Berkeley, said in an email. Nemeth, the author of the 2018 book In Defense of Troublemakers, added, “People who speak up are often those most loyal to the organization.” Read the whole story: The Atlantic At one point, Isaacson wrote, she found out that Jobs had adjusted her marketing projections “in a way she found totally reality-distorting.” As she marched toward his office, she told his assistant, “I’m going to take a knife and stab it into his heart.” The company’s counsel overheard her and rushed out to stop her. “But,” she told Isaacson, “Steve heard me out and backed down.” The next year, she won the award again.last_img read more

KMC to start Aadhaar enrolment camps in borough offices from May

first_imgKolkata: The Kolkata Municipal Corporation (KMC) will start holding camps for Aadhaar enrolment at its borough offices in the city, from the beginning of May. The decision of the civic body comes in the wake of demand for citizens to introduce such facilities for smooth enrolment and correction of erroneous names, addresses or other details in the Aadhaar cards.”We have been flooded with requests from citizens, who have claimed that they had paid visits to the designated post offices where such enrolment centres have been set up and many of them had to wait for a long time in queue. Many people have visited our borough offices in recent times, urging us to make arrangements. Following this, we had written to the state government, seeking permission for such arrangements. We have recently got the nod,” a senior official of KMC said.

There were more than twenty private agencies working under KMC for Aadhaar enrolment. However, after the circular, the civic body was compelled to stop such enrolment process. As per data available with KMC, 80 percent of the population in KMC area have got their Aadhaar cards and 20 percent are yet to receive the same. Added to this, the people gather in the enrolment centres for correction in their cards, which includes mistakes in names, addresses etc. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedAccording to a senior KMC official, from January till March, only two private agencies were involved in Aadhaar enrolment, but these two agencies have also been deactivated after March 31.
