Scientists discovered a extraterrestrial Similar to this Thursday And more than 2 thousand degrees of heat Sol. The findings were published in the journal Natural AstronomyIt can help to understand better Evolution of planets And this Stars In extreme conditions.
How is an exoplanet hotter than the Sun?
He extraterrestrial Inside is a binary system Formed by two celestial bodies located approximately 1,400 light years away. The researchers found that using spectroscopic data collected by A very large telescope of European Southern ObservatoryIn Chile.
“Here we report observations that this object near the hydrogen burning limit reveals a very radiative low-mass companion to the hot white dwarf WD 0032–317 (…), which may be one of the most massive brown dwarfs known.”

This is binary system The most extreme of its class known so far in terms of temperature, according to the researchers it will be almost 2 thousand degrees higher than the surface of the Sun.
The exoplanet is similar to Jupiter… but not quite
Unlike others Extraterrestrials Similar to this Thursdayetc KELT-b9 (Jupiter Caliente)It can be observed and studied extraterrestrial Due to its large size compared to the host star it orbits, approx 10 thousand times weaker than an ordinary star.
“It has a daytime temperature of ~8 thousand K and a day-night temperature difference of ~6 thousand K. The amount of extreme ultraviolet radiation received by WD 0032-317B is equivalent to that received by hotter planets orbiting near stars. Recent B-type stars, and KELT- 5,600 times hotter than 9b.”

What are white dwarfs and brown dwarfs?
A”white dwarf” is the remnant of a Sun-like star after it has exhausted its nuclear fuel; The other part of this pair, which is neither a planet nor a star, is a “Brown dwarf”, a member of a class of objects with masses between those of a Jupiter-like gas giant and a small star.
los”Brown dwarfs” are sometimes called failed stars because they do not have enough mass to fuel hydrogen fusion reactions, but unlike gas giant planets, they have enough mass to survive the “pull” of their stellar companions, the report said. Weizmann Institute of Science.
Items like this A Jupiter-like exoplanet According to the researchers, they are the opposite of habitable planets because they are “dramatically inhospitable places for life,” he said. Nama Hallakonfrom the Department of Particle Physics and Astrophysics at the Weizmann Institute of Science.
Future high-resolution spectroscopic observations A hot system like Jupiterr can reveal how hot and high radiation affects conditions Atmospheric systemSomething that helps the scientific community understand Extraterrestrials In other parts of the universe.
