Effect of distortion to pulsation period in eclipsing algols with pulsating component

The effect of rotation and tide to the pulsation frequencies of pulsating components in Algols and other binary strars is investigated in this study. The variation of frequency and amplitude with fundamental quantities like mass ratio, central distance is studied and this quantities are connected to each other for changing frequencies and amplitude. Observational evidence to theoretical model is searched and it is tried to proof the effect by using the observational data. The results show that the frequency and amplitude observable on the surface of the star vary slightly for distorted stars when compared to undistorted ones.
