Abstract

This article presents photometric studies of the cataclysmic variable 2MASS J02253615+2805508, which belongs to nova-like. The light curve is modeled based on the fact that the binary system consists of a primary and secondary star, an accretion material flow, an accretion disk, and a hot spot on its edge. Taking into account the distance to the star taken from the results of the Gaia mission, equal to d=315 (5) pc, some system parameters are obtained, such as the inclination of the system i=77.2°, the masses of the primary and secondary stars, M1= 0.70 Mʘ and M2=0.42 Mʘ, respectively, the radius of the accretion disk Rdisk= 0.58 Rʘ.
