Scientific paper

The paper contains a model synthesizing the light curves of the active close binary (CB) AR Pav in the phase of an intensive matter exchange between the components, with accretion onto the primary star. The model considers the radial and azimuthal temperature distributions in the disk enabling a successful interpretation of the asymmetrically deformed light curve characteristic of this system. The analysis of the observed light curves is performed by using the inverse-problem method adapted to this model. The parameters for AR Pav are estimated on the basis of photographic observations. The synthetic light curves obtained through the inverse-problem solving, as a whole, fit the observations well which suggests that the existence of an accretion disk around the primary of AR Pav is possible.
