Emoji of the sun is the hottest brown dwarf ever observed so far A planet-like object hotter than the sun, according to a report published in the journal Nature Astronomy. Scientists have found a brown dwarf called WD0032-317B, and this object is located 1,400 light-years away. The brown dwarf orbits its host star so closely that it reaches an incredibly high temperature of more than 8,000 degrees Kelvin, about 2,000 degrees hotter than the surface temperature of the sun. It is the hottest brown dwarf ever observed to date. Interplanetary objects Brown dwarfs are classified as interplanetary objects, and although they are hotter than planets, they cannot reach the temperatures of stars. The discovery of WD0032-317B provides Valuable insights into the behavior of gas giants, such as Jupiter, that orbit hot, massive stars. These observations are often difficult because of the stars’ brightness and activity. The extreme environment around these exoplanets can cause their atmospheres to evaporate and break up the molecules due to the intense ultraviolet radiation they receive. An opportunity for scientists WD0032-317B represents an opportunity for scientists to study such extreme environments, as its companion is a white dwarf star, called WD0032-317, It is smaller and fainter, with a mass of only 40% of the mass of our sun, but it is hotter than it, with a temperature of about 37,000 K (for comparison, the surface of the Sun is about 5,778 K). Brown dwarfs differ from planets and stars. It has enough mass to ignite the fusion of deuterium, a process involving the heavy isotope of hydrogen, but it does not have the same fusion reactions as stars. Its temperature can reach about 2,500 K, and its mass is 80 times the mass of Jupiter. And white dwarfs, on the one hand Others, are remnants of stars and could have temperatures similar to blue giant planets. In the early 2000s, observations with the Ultraviolet-Visible Spectrograph instrument Echelle Spectrograph on the European Southern Observatory’s Very Large Telescope revealed WD0032-317, and that it was being influenced by a companion. Invisible.These are his qualities Recent observations, published in a research paper in the journal Nature Astronomy, confirmed that this companion is a brown dwarf, not a companion star, whose mass is between 75 and 88 Jupiters. The proximity of the brown dwarf to its host star causes it to be tidally locked, which means that the same side of the planet is constantly facing its star. Maximum daytime temperatures range from 7,250 to 9,800 K (about 7,000 and 9,500 degrees Celsius), and it is hot. Such as A-type stars, sun-like stars that can be twice the mass of the Sun and hotter than any known giant planet. On the other hand, the temperature of the night side ranges between 1,300 and 3,000 K (about 1,000 and 2,700 degrees Celsius), which leads to an extreme temperature difference of about 6,000 degrees between the two hemispheres. The WD0032-317B study can provide valuable insights into how hot stars To evaporate the atmospheres of smaller companion bodies. Read also
