| Summary: | In this thesis we discuss the properties of a radiation-driven stellar wind in an X-ray binary system. Using the parameters appropriate for the high mass Xray binary system Cygnus X-1, the effects of the compact companion on the stellar wind are examined. We have developed a full 3D hydrodynamic model of circumstellar mass based on a modified version of the Castor, Abbott & Klein line-driven mechanism. The effects of the compact companion - gravity and continuum radiation pressure - as well as the centrifugal and Coriolis force due to orbital motion are included. These forces subvert the spherical symmetry of the wind and lead to significantly different results then previous strictly radial hydrodynamic simulations. |
