Another contender is the white dwarf at the center of the . This object's surface has been measured at over 200,000 degrees Celsius , more than 30 times hotter than our Sun. Its extreme temperature makes it glow extraordinarily bright: intrinsically more than 250 times brighter than our parent star. These stars are so hot that they do not merely absorb light; their photospheres exhibit emission lines in the ultraviolet spectrum, a phenomenon rarely seen in stellar astronomy.

After a star exhausts its nuclear fuel, it sheds its outer layers, and the core collapses into an incredibly dense, Earth-sized object. A typical white dwarf packs a mass comparable to the Sun into a volume similar to Earth. This matter is so compressed that it is supported not by nuclear fusion, but by a quantum mechanical effect called electron degeneracy pressure , which prevents further collapse. white dwarf 137 pdf hot
