| Abstract: |
O(He) stars are unique amongst the hottest post-AGB stars because their atmospheres are
composed of almost pure helium. We present a spectral analysis of HST/COS UV
observations by means of NLTE model-atmosphere techniques and discuss their status
in the hydrogen-deficient post-AGB evolutionary sequence and in the double-degenerate
merger scenario. |
