Scientific paper

The paper is devoted to the problem of the determination of the orbital and physical parameters of the active CB OO Aql on the basis of the interpretation of photometric observations made by Lafta and Grainger (1985). The problem is solved in two stages: by obtaining a synthetic light curve in the case when the parameters of the corresponding CB model (Djurašević, 1992) are given a priori (direct problem) and by determining the parameters of the given model for which the best fit between the synthetic light curve and the observations is achieved (inverse problem) (Djurašević, 1992). The light curves are analysed in the frame of several working hypotheses among which the hypothesis including a hot spot on the secondary proved to be the probable one. Within the last hypothesis the basic parameters of the system and of the active region are estimated.
