Sooo Hot!

In September of this year, the galaxy's hottest white dwarf was discovered by astronomers from the universities of Potsdam and Tübingen. This came from analysis of spectra analyzing the edge of the Milky Way, in which they discovered a relatively small, but very hot star in its cooling phase. This star (RX J0439.8-6809) was measured to be around 250,000K, although it is estimated that at its peak the temperature was around 400,000K. A star of such low density and such high temperature is indicative of something originating very far from us; indeed, this was found to be a part of a larger gas cloud moving towards the Magellenic cloud structure. Not much is known about the formation of this unusual star beyond that.
