WD 0806-661 B, the coldest star ever discovered
KOMPAS.com - Humans might be living in a star. Astronomers have discovered a star that its temperature matches live human being. The star is named WD 0806-661 B.
Associate Professor for Astronomy and Astrophysics Pennsylvania State University, Kevin Luhman, who found the star says, "This is a very small star with temperatures as cold as the Earth's atmosphere."
Stellar mass is only 6-9 times the mass of Jupiter. In fact, the star has been named the coldest star outside our solar system ever found. Luhman said the star was classified as the type of brown dwarf stars.
Like other stars, WD 0806-661 B is also formed from clouds of dust and gas. Temperatures can be cool star. Because, in the process of its formation, the star failed to accumulate a mass of dust clouds that thermonuclear reactions do not occur. Star temperature is estimated only 27-80 degrees celsius.
WD 0806-661 B orbiting a white dwarf star. The distance between the WD 0806-661 B and diorbit white dwarf star is 2,500 times the distance between the Earth Sun. To be able to determine whether this is worth habitable star, definitely still needs a lot of research. However, white dwarfs are located quite close to the Solar System, only 63 light years, so more "affordable".
WD 0806-661 B found with NASA's Spitzer Space Telescope. The results published in the Journal Astrophosical. WD 0806-661 B itself has been confirmed as the coldest star.
