摘要：
We review our current knowledge about hot helium rich (DO) white dwarfs. For most known DOs detailed NLTE model atmosphere analysis have now become available. These stars represent the non-DA white dwarf cooling sequence from the hot end (T-eff approximate to 120000 K) down to the DB gap (T-eff approximate to 45000 K). Determination of effective temperature, surface gravity and metallicities allow a comprehensive comparison with predictions of diffusion calculations.
