White dwarf considered the hottest ever discovered

Astronomy & Astrophysics has published spectroscopic observations of one of the hottest stars discovered so far - a white dwarf called KPD 0005+5106. The observations were made using the space-based Far-Ultraviolet Spectroscopic Explorer (FUSE), showing that the temperature can reach 200 000 K at the surface of the star. Temperatures can get so high that [...]
