AN ANALYSIS OF CLOSE BINARIES (CB) BASED ON PHOTOMETRIC MEASUREMENTS .4. AN INTERPRETATION OF CB LIGHT-CURVE AG VIR BY USING THE INVERSE-PROBLEM METHOD

The paper is devoted to the actual problematics in the determination o f orbital and physical parameters of active CB on the basis of the int erpretation of photometric observations. One solves the problem in two stages: by obtaining a synthetic light curve in the case when the par ameters of the corresponding CB model are given a priori (direct probl em) and by determining the parameters of the given model for which the best fit between the synthetic light curve and the observations is ac hieved (inverse problem). In this paper, the above procedure is applie d to a particular case of CB AG Vir.
