Multi-dimensional Radiation Transfer in the Expanding Envelopes of Binary Systems

  • R. Baade
Part of the Reviews in Modern Astronomy book series (MOD.ASTRONOMY, volume 2)


A generalized integral-operator method is developed to solve the radiative transfer problem in non-symmetric envelopes with arbitrary velocity fields. The major goal of this research is to design an improved radiation transfer code for the UV binary technique of studying mass-loss phenomena of late giants and supergiants. The application to the ζ Aur configuration requires a two-dimensional approach since the light source (B star) is offset from the centre of symmetry of the wind. First results for the system 32 Cyg yield a consistent fit of line profiles.
