Non-LTE Analysis of Hot Stars Including Line Blanketingning these effective opacities with an atmosphere code that solves the statistical equilibrium equations for non-LTE populations and the radiation transfer equations in the comoving frame, we obtain a model atmosphere that accounts simultaneously and consistently for non-LTE, spherical extension, expansion, and line blanketing.

Acceleration of Convergenceugate vector spaces are presented. It is shown that both give dramatic improvement, at very low computational cost, in the iterative solution of radiative transfer problems in the presence of scattering.

Fast Solution of Radiative Transfer Problems with a Multi-Grid Methodomogeneous slab, and a grey 2-D LTE model atmosphere in radiative equilibrium. The multi-grid method (W-cycle) is a combination of coarse grid corrections and smoothing steps, the latter being accelerated Λ-iterations. In contrast to classical acceleration schemes the present method makes use of the

NLTE Spectral Line Formation in Three Dimensionshe solar photosphere is used as an illustration of a method which converges in few iterations, each of which requires a time which scales linearly with the number of degrees of freedom in the problem. The importance of Doppler shifts in providing increased opportunity for spatial couplings is stress

Analysis of Ultraviolet P Cygni Profiles in the Spectra of O-Type Starse profile fitting technique. We then point out that, if we want to make a proper statistical study of the UV P Cygni profiles observed in the spectra of O-type stars, we have to take into account the severe pollution effects due to a forest of FelV and FeV absorption lines. We discuss a method allow
