Metal abundances in the hottest known DO white dwarf (KPD0005+5106)
The extreme temperature of the star and a very weak stellar wind suffice to prevent differential diffusion of elements, and this is the hottest temperature yet for a post-AGB star. Its abundances, except for Fe, show close links to those of the R CrB stars that are possible AGB pregenitors of such hot stars.
