Unified NLTE Model Atmospheres Including Spherical Extension and Stellar Winds: EUV — Fluxes and thee. The models are of spherical geometry and extended over the entire sub- and supersonic atmosphere. They need only stellar effective temperature, gravity, radius and helium abundance as free parameters and are in principle self-consistent. We have calculated a large grid of models for Central Stars

Non-LTE Model Atmosphere Calculations with Approximate Lambda Operatorste lambda operators and a new numerical approach for the linearization procedure are presented..The optimum . approximate lambda operator was found by Olson & Kunasz (1987). An increase in convergence rate is only possible with . approximate lambda operators. The introduction of tridiagonal operator

NLTE Model Atmospheres for Hot Starsre we present recent results of our NLTE model atmosphere calculations for hot sdO stars including very elaborate C IV, N IV and N V model ions simultaneously in order to determine the ../.. and ../.. abundance ratios.

Time-Dependent Two-Dimensional Radiation Hydrodynamics of Accreting Matter onto Highly Magnetized Neaccretion of matter onto the highly magnetized polar caps of luminous x-ray pulsars. The calculations show a structure in the accretion column very different from previous one-zone uniform models. We have included all the relevant magnetic field corrections to both the hydrodynamics and the radiativ
