© 2016 Phys.org EPIC 212803289 is a bright, metal-rich subgiant star located some 1,970 light years away in the constellation Virgo. Although the star has a temperature similar to the sun, it is about three times larger and is approximately 1.6 solar masses. It was identified by NASA’s prolonged Kepler mission, called K2, as a good candidate to host an alien world. However, the existence of a potential exoplanet must be confirmed by follow-up observations.”Following the identification of the system as a candidate, it was necessary to make radial velocity measurements to confirm the planet and measure its mass. These observations were performed with four different ground-based telescopes (on La Palma, Spain, in Chile, and in Texas, U.S.),” Smith told Phys.org.The newly found exoworld, designated EPIC 212803289 b, is similar in size to Jupiter, with a radius of 1.29 Jupiter radii and is only 3 percent less massive than our solar system’s biggest planet. The object orbits its parent star every 18.25 days.The scientists estimated that the exoplanet’s temperature is about 1,000 degrees Celsius and classified it as a so-called ‘warm Jupiter’ However, it is possible that the planet is even hotter, as it could be tidally locked, meaning that one of its sides permanently faces the star, while the other side experiences permanent night.”In this case, the day side could be even hotter (up to 1,350 degrees Celsius), depending on how good the planet’s atmosphere is at redistributing heat from the day side to the night side,” Smith said. He added that the host star will soon expand to become a red giant, enlarging so much that it will engulf the planet. This will happen relatively soon in astronomical terms—in about 150 million years.Furthermore, besides detecting EPIC 212803289 b, Smith’s team suspects the existence of another companion of the star. Based on measured systemic radial acceleration, they assume that there is a third body in the system with an orbital period of more than 236 days and a mass of more than 22 Jupiter masses. They noted that it could be a brown dwarf orbiting within 2.7 AU, a solar mass object at about 10 AU, or an object orbiting on a highly-eccentric orbit.According to Smith, further radial velocity observations of this system over the next year or two would probably reveal the nature of this body.The new research is significant for our understanding of extrasolar systems, as EPIC 212803289 b is the newest addition to a currently small number of planets known to transit subgiant stars. So far, only 31 transiting planets of stars more massive than 1.5 solar masses have been detected. Moreover, only four planets are known to transit giant stars, and a further three transiting planets are known around subgiants.”Understanding gas giant planets requires large numbers of detections, so that statistics can be performed. Especially, detections are needed that expand the parameter space of known systems—e.g. planets around different types of star (such as subgiants in this case), and at longer periods than hot Jupiters. It is also important that such systems are discovered around relatively bright stars, to allow further characterization observations. Progress is incremental, but this new system is an important addition to the catalogue of known gas giants,” Smith concluded.

(Phys.org)—A team of astronomers led by Alexis Smith of the German Aerospace Center’s (DLR) Institute of Planetary Research in Berlin reports the detection of a Jupiter-like planet orbiting a distant subgiant star known as EPIC 212803289. The researchers also present compelling existence for the existence of a third body in the system, most likely a brown dwarf. The results were published Sept. 1 in a paper on arXiv.org.

We confirm the planetary nature of the companion with radial velocities, and determine that the star is a metal-rich ([Fe/H] = 0.20±0.05) subgiant, with mass 1.60+0.14−0.10 M⊙ and radius 3.1±0.1 R⊙. The planet has a mass of 0.97±0.09 MJup and a radius 1.29±0.05 RJup. A measured systemic radial acceleration of −2.12±0.04 ms−1d−1 offers compelling evidence for the existence of a third body in the system, perhaps a brown dwarf orbiting with a period of several hundred days.

Cotton thread is made of many tiny fibers, each just 2-3 cm long, yet when spun together the fibers are capable of transmitting tension over indefinitely long distances. From a physics perspective, how threads and yarns transmit tension—making them strong enough to keep clothes from falling apart—is a long-standing puzzle that is not completely understood. Citation: Researchers investigate ‘why clothes don’t fall apart’ (2018, April 23) retrieved 18 August 2019 from https://phys.org/news/2018-04-dont-fall.html In a new paper published in Physical Review Letters entitled “Why Clothes Don’t Fall Apart: Tension Transmission in Staple Yarns,” physicists Patrick Warren at Unilever R&D Port Sunlight, Robin Ball at the University of Warwick, and Ray Goldstein at the University of Cambridge have investigated yarn tension in the framework of statistical physics. Using techniques from linear programming, they show that the collective friction among fibers creates a locking mechanism, and as long as there is sufficient friction, a random assembly of fibers can in principle transmit an indefinitely large tension.Their results provide a quantitative basis for the heuristic explanation proposed by Galileo in 1638, who was puzzling over the problem of how a rope can be so strong when it is made of such small fibers. “The very act of twisting causes the threads to bind one another in such a way that… when the rope is stretched… the fibers break rather than separate from each other,” he wrote. In modern terms, Galileo was describing friction.In the new study, the researchers modeled the yarn as a group of randomly overlapping fibers. The results showed that, as the friction increases, a percolation transition emerges. As the researchers explain, this transition corresponds to “a switch from a ‘ductile’ failure model where the yarn fails by fiber slippage… to a ‘brittle’ failure mode where the failure mechanism is fiber breakage.” Above this threshold, the tensile strength becomes roughly 100 times stronger than before.”We now understand better at a fundamental level how friction stops fibrous materials from falling apart,” Goldstein told Phys.org. “From an applied perspective, we can use the insights to underpin the design of fabric conditioners, for example.”In the future, the model could also be used to optimize the properties of sewing threads made of various fiber blends. When extended from fibers to granular media, the results may also have applications for better understanding the stress transmission in sand piles and grain silos. In addition, the researchers plan to investigate the threshold in greater depth.”We plan to write a longer paper exploring the nature of the ‘supercritical’ state, above the percolation transition,” Goldstein said.

Including facial oil in your daily beauty regime helps to combat damage to facial skin like ageing. Facial oil can be beneficial in all aspects, says an expert.Good quality facial oil tricks the skin into thinking that it’s produced enough and therefore doesn’t need to produce more – which is one of the major reasons for the skin’s breakouts. Thus, it is ideal to use facial oils regularly as they help in rejuvenating the skin and due to the application procedure, help in relaxing the facial muscles. Also Read – Add new books to your shelfFacial oils are an excellent way to massage anti-oxidants and vitamins quickly into the skin, at the same time adding a natural glow and helping to save the skin from ageing.The oils get absorbed quickly and soften the appearance of fine lines. Due to the daily massage, they also help lift the facial muscles and make them firmer. Facial oil also has the ability to reduce redness, irritation and even breakouts. Vitamin E is highly beneficial as it is a powerful anti-oxidant that helps repair cell damage. Facial oils usually have the ever nourishing vitamin E, marula oil, Argan oil, rosehip, camellia, black cumin among other things.Facial oils are best for every skin type (dry, oily or combination) as they rebalance skin and restore a naturally healthy complexion. Moisturisers, lotions or crèmes and facial oils can be used simultaneously as facial oils are great for layering. It is best to apply oil right after freshly cleansing the skin in the morning and at night before applying the moisturiser.
Kolkata: Telangana Chief Minister and TRS chief K Chandrashekhar Rao met his Bengal counterpart and Trinamool Congress supremo Mamata Banerjee on Monday and said that the dialogue over formation of a Federal Front for the 2019 Lok Sabha elections will continue.”Our dialogue will continue and very shortly we will come out with a concrete plan. We are discussing things…a non-Congress, non BJP front is my mission. I will continue my efforts,” Rao said after meeting Banerjee at the state secretariat Nabanna. Also Read – Rain batters Kolkata, cripples normal lifeHe reiterated that an alternative front to the Congress and BJP-led alliances is not a small matter. “Wait for the right time. The dialogues will continue,” he told reporters with Banerjee and some senior ministers of the state government beside him. Rao, popularly known as KCR, has achieved a resounding victory in the recently-concluded Telangana Assembly polls, and is now working on forming an alternative coalition front ahead of the 2019 general elections. He had also met his Odisha counterpart and Biju Janata Dal (BJD) chief Naveen Patnaik, at his residence in Bhubaneswar on Sunday.

Since he is visiting the national capital for the first time after the Assembly elections, he will also be making a courtesy call on Prime Minister Narendra Modi. It may be mentioned that Mamata Banerjee has been talking about the formation of the Federal Front from early this year. Chandrababu Naidu has already met Mamata Banerjee and on Saturday, Farooq Abdullah met her as well and discussed about the functioning of the Federal Front. Many national leaders who will join the Front will come to attend the Brigade Parade Ground Rally, scheduled to be held on January 19, 2019.
Despite claiming to support gay rights, many straight people who live in predominantly gay neighbourhoods still practice subtle forms of discrimination when interacting with their gay and lesbian neighbours, researchers have found. According to research published in the journal City and Community, straight people living in “gaybourhoods” interact withtheir gay and lesbian neighbours on the street in ways that contradict the sentiments of supporting them. Also Read – Add new books to your shelf”There is a mistaken belief that marriage equality means the struggle for gay rights is over. But it is far from over. Prejudice and discrimination still exist – it is just more subtle and difficult to detect,” said Amin Ghaziani, the study’s senior author from the University of British Columbia in Canada.The researchers interviewed 53 straight people and found the majority of residents said they supported gay people.However, their progressive attitudes were misaligned with their actions. While many residents said they did not care if people were gay or straight, some indicated that they did not like gay people who are “in your face.” Also Read – Over 2 hours screen time daily will make your kids impulsiveWhen asked about resistance from lesbian, gay, bisexual, transgender, questioning/queer (LGBTQ) communities to the widespread trend of straight people moving into “gaybourhoods”, some of the people interviewed responded with accusations of reverse discrimination and described gay people who challenged them as “segregationist” and “hetero-phobic.””If a group of straight women hosted a bachelorette party in a gay bar, for example, they were surprised that they felt ‘unwelcome,'” added Ghaziani. “That feeling of surprise, however, exemplifies a misguided belief that gay districts are trendy commodities when they are actually safe spaces for sexual minorities,” he added.Many expected their gay and lesbian neighbours to be happy and welcoming of straight people moving into “gaybourhoods”.Ghaziani said this argument exemplifies the fundamental misunderstanding of the inequality and discrimination that creates the need for “gaybourhoods” in the first place.
