Abstract

The DAO-type white dwarf LS V+46° 21 is the hydrogen-rich central star of the possible planetary nebula Sh 2--216. We have taken high-resolution, high-S/N ultraviolet spectra with STIS aboard the HST and FUSE in order to constrain its photospheric parameters. A detailed spectral analysis by means of state-of-the-art NLTE model-atmosphere techniques is presented which includes the determination the individual abundances of iron-group elements.
