According to Sputnik (Russia), located 1,400 light years from Earth, the newly discovered brown dwarf is named WD0032-317B. This object was discovered by a team of researchers, astrophysicist Na'ama Hallakoun at the Weizmann Institute of Science (Israel).
Specifically, the brown dwarf WD0032-317B orbits its host star so closely that it maintains a temperature above 8,000 Kelvin (7,727 degrees Celsius). Officials note that this temperature is hot enough to break down molecules in the atmosphere into synthetic atoms. Meanwhile, the temperature of the Sun is only 5,778 Kelvin (5,505 degrees Celsius).
As a result, this brown dwarf has broken the record for the hottest object in the universe. Brown dwarfs are generally hotter than planets, but they are still cooler than the coolest red dwarfs.
Previously, NASA described brown dwarfs as small, low-mass stars that are intermediate between the gas giants. Brown dwarfs have masses between 13 and 80 times that of Jupiter. Although many brown dwarfs have been discovered so far, such hot objects orbiting other stars are rare.
These celestial bodies are often difficult to observe because of their low energy and light output. In fact, scientists first discovered brown dwarfs in the late 1980s.
In addition to the exciting discovery of this unusually hot object, the team of astronomers has claimed that the brown dwarf WD0032-317B could help them better understand the planet Jupiter, as well as other gas giants orbiting large, hot stars that are difficult to study due to their activity and rotation rates.
