... HS2253+8023 is a helium-rich white dwarf with traces of metals and hydrogen, which was recently discovered in the Hamburg Quasar Survey. We have derived temperatures and element abundances from optical and UV spectra by comparison with synthetic line profiles. In addition UV (HST, IUE) and optical spectra of the well-known white dwarf GD 40 with very similar atmospheric parameters were analysed and element abundances determined. ...
