Modelling of light and radial velocity curves of interacting close binary systems


E.A. Antokhina

We present the results of light curve analysis, which allows us to determine stellar masses for interesting massive binary system containing massive early type components HD93205 and the results of X-ray light curves analysis of the unique object SS433 obtained by the INTEGRAL space observatory. We also present modeling of theoretical absorption-line profiles and radial velocity curves of optical components in X-ray binary systems, which was carried out with our new computer code. Сomparing observed line profiles and radial velocity curves with the model ones provides a possibility to correctly determine masses of relativistic objects.
