Active close binaries (CB) models and methods for interpretation of the photometric observations.
Abstract
An essential progress in CB evolution theory started about 1970 thanks to the development of computer models enabling synthesizing of the light curves and those of lineofsight velocity. These models, based physically on the Roche equipotentials, appear as substitutions for the traditional geometrical models. The progress in the understanding of the physical processes in CBs is closely connected with the development of the physical model for synthesizing of light curves and those of lineofsight velocities. The interpretation of the observations is reduced to two crucial problems: one should first develop an adequate model for synthesizing a light curve or that of lineofsight velocity (direct problem) and then by applying a corresponding optimization model to estimate the parameters for which the chosen model yields the best fit to the observations (inverse problem). In this review the models and methods for interpreting the observations of active CBs are stressed.
