| Abstract: |
Possibility to derive the physical parameters of the binary system components from an analysis of the orbital light curves is shown on the example of well-known dwarf nova SS Cyg. It was done by approximation of the observed light curves by synthetic light curves constructed in frame of classical hot-spot model. The shape of the light curves of SS Cyg is mainly determined by ellipsoidal variations of the optical component. Despite of the contribution of the hot spot to the total optical flux of this system is rather small, eclipses of the hot spot (between orbital phases 0.1–0.6) distort the pure ellipsoidal light curve of SS Cyg. Account for such distortions allows us to derive parameters of the binary components (masses, radii and temperatures) more precisely. |
