The ancient "super-zero" eclipter has found a nearby star's orbit



[ad_1]

The nearest star of the Sun is like a huge, glaciated planet.

Astronomers have discovered evidence of a cold-blooded world in the world. Barnard's star is massive around the Earth around 3.2 times, with 6 light years from sunlight. Barnard's Star is our closest neighbor. Apart from the six-centimeter Alpha Centauri, it is about 4.3 light years.

Barnard remains the newest known planet star in the world called Star B. However, researchers who have noticed it are convinced that a strange planet will finally be confirmed. [Barnard’s Star b: What We Know About the “Super-Earth’ Candidate]

Ignasi Ribas of the Catalonia Institute of Space Studies and the Spanish Space Science Institute say that "after a careful analysis, we are 99 percent sure that the planet exists.

"But we will continue to exclude the incredible, but incredible, natural, brightness that can turn into a masquerade like this super-motionless star," said Star Barnard's star. This study was published today in the journal Nature (November 14).

New impressions of the artist

If Barnard is confirmed by Star b, there will be no closest exoplanet for Earth. This designation is based on Proxima Centauri, a middle-sized Land of Proxima b, which turns into an orbit from the Alpha Centauri Trio.

NASA's Kepler space telescope has shown that small planet in the Saryagaz galaxy is widespread. In addition, Proxima b and Barnard & nbsp; s are such worlds as "our neighbors are widespread," says Joanna Tesse, the author of the Earth Magnetism Department at the Carnegie Institute in Washington, DC. – And it is very interesting.

The sun closest to the neighbor

Barnard's Star American astronomer EE Named after Barnard, which determined the speed of Ribas in 1916. None of the stars in the sky in the sky will pass quickly, as the snake's width is 180 years, according to Barnard Star. [Gallery: The Strangest Alien Planets]

This incredible motion – the Barnard star and its high (but not-in) speed depend on the distance of 310,000 miles per hour (500,000 km / h).

January 1, 2: Sverdlovsk / Full Wolf Moon

The moon is the closest to the Earth in the new year and is much more common than the usual and differs from the "Supermoon".

Also, any first full moon will be different from the "Full Wolf Month". The term was persuaded by the Americans in January for wolf-wolfs that they often hear outside of their village.

January 3, 4: Quadrantids Meteor shower

Quadrantid, the meteorite known to produce 50-100 meteors at the highest peak, is the first large meteor shower in 2018.

Unfortunately, the full-length light lasts for most of the show.

HIDE CAPTION

Show CAPTION

Barnard's star brings us closer every day: in about 10,000 years, the red dwarf gets the nearest star mantle from the Alpha Centauri system. At that time, 3.8 light years are separated from Barnard & # 39; s Star.

The star of Barnard is about twice as high as the Earth, about a sixth of an array, and only about 3 percent of the Earth's surface. As Barnard's star is so dark, his "living space" – the range of possible distances in the world of liquid water – is very close. Indeed, researchers believe this region is a gateway from 0.06 AU to 0.10 AU. (One AU or astronomical unit Earth-Sun distance – about 93 million miles or 150 million kilometers.)

The concept of a residential area is certainly difficult. Assessing the true lifestyle of the world requires the presence of atmospheric composition and thickness among its other attributes. Such information is extremely difficult to exaggerate.

Long search

Barnard Star has long been a target of hunting for hunters, but their tracks are always free.

It was not easy to find a new one: Ribas and his team analyzed a large amount of archived and newly collected data, eventually dumping Barnard & # 39; s Star.

They used the "radial velocity" method to search for star changes from the orbital planet's gravitational tube. These towers strike a bit of a star, its brightness sometimes shifts to the red wavelength and moves to another color like the Earth on the blue. [7 Ways to Discovery Alien Planets]

"We have created the largest and most widely used data collection tool for these radionum-velocity research and monitored the 20-year scale with seven different tools," said Ribas. "The total of all the data has reached a total of 771 measurements – a great deal of information!"

Such a method of determining such a cosmic planet's radar velocity has never been found on an unprecedented orbit. (Large, nearby planets enhance their ownership and thus dramatically and easily identifiable, resulting in easy replacement.)

These seven tools are the High Accuracy Radar Searching Tool (HARPS) at the La Silla Observatory in the European Southern Observatory (ESO) in Chile; ultra-violet and visual torque spectroscopy on a very large telescope; ESO paranoid observatory in Chile; On the Galileo national telescope in Canales, HARPS-North; Keck in Hexa, a high-resolution echolle spectrometer with a 10-meter telescope; The Spectrum of the Carnegie's Planet's Finding is on the 6.5-m Magellan Telescope at Las Campanas Observatory in Chile; An automated planet search tool on a 2.4 m telescope at the California Lik Observatory; and CARMENES at the Calar Alto Observatory in Spain.

The researchers have also identified other possible plan tips in the system, which is not far from Barnard's star, orbital 6,600 Earth Day. But this is the second sign that the planet is considered a weak candidate, says Teske.

"There is not enough data available," Space.com said.

Cold super-earth

Barnard Starb has at least 3.2 times larger than our planet, much larger than the Earth, but smaller worlds, such as Neptune and Uranus, can be "super-zero".

Candidate for the newly discovered planet, reaching 0.4 AU, completes one orbit on its 233 Earth days.

This orbital distance radiated Mercury is similar to our own solar system. However, Barnard's Star is very dark, so the potential planet is located in a zone where the "snow line" of the system can become a solid substance, such as porous materials.

Rodrigo Dias, a scientist from the Institute of Astronomy and Space Physics, at the National Research and Research Council of Argentina's Buenos Aires University, said: "Until now, only remote planets have been discovered." He has also published an article entitled "News and Views" published today in Nature.

"Discovery of the planet's lower planets in the vicinity of snow, strongly hinders the formation of models for this type of planet," added Diaz, who did not participate in new studies.

Barnard's Star B, in fact, is a very promising place for life, not at least on the surface. The potential planet is probably very cold, about Fahrenheit (minus 170 degrees Fahrenheit) to a minus 275 degrees Celsius.

As Dias notes, Barnard's Star B can not be obtained from additional radial velocity measurements. However, as the space agency has developed the spacecraft "Guy", the actual dimensions of the star positions can work in the next few years, "he said.

According to Diaz, "the next generation of surface installations to be launched in 2020 should be capable of directly depicting the planet and measuring its light spectrum."

"Using this spectrum can be used for the atmosphere of the planet, such as wind and speed of rotation," he said. That miraculous planet can therefore be one of the first mass exothermals of the atmosphere, which has an important part in the formation and evolution of the planets. "
