Аннотация: Synthesis methods for light and radial velocity curves are currently one of the main tools for studying close binary systems (CBSs). The paper gives a brief review of the history and development of the methods and their implementations in Sternberg Astronomical Institute of Moscow State University (SAI MSU), where a set of computer programs has been created to analyze observations of CBSs of various types. As a demonstration, we present the results of the analysis by our algorithms for three interesting CBSs at different evolutionary stages. An analysis of the unusual light curves of the recently discovered pre-cataclysmic binary GPX-TF16E-48 was performed using the Roche model with spots on the normal star. The X-ray light curves of the microquasar SS433 were analyzed using a precessing accretion disk model. The highly elliptical Wolf-Rayet binary WR22 was studied in the frame of the Roche model accounting the absorption by the powerful wind from the Wolf–Rayet star using space-based photometric observations. As a result of this detailed anal-ysis of the light curves and involving spectroscopic information, the parameters of the CBSs and their components were found. This paper is based on a presentation made in the astrophysical memorial seminar “Novelties in Understanding the Evolution of Binary Stars,” dedicated to the 90th anniversary of Professor M.A. Svechnikov.
