H1504+65
H1504+65 is an enigmatic peculiar star in the constellation Ursa Minor. With a surface temperature of 200,000 K and an atmosphere composed of carbon, oxygen and 2% neon, it is the hottest white dwarf ever discovered. It is thought to be the stellar core of a post AGB star, though its composition is unexplainable by current models of stellar evolution. ==References==
