First light curve analysis of the high-amplitude Delta Scuti star GSC 4552-1498

We carried out observation of the HADS (High-Amplitude Delta Scuti) variable GSC 4552-1498 through three filters. Our goal was to consider its periodic behavior using our photometry data in addition to previous observations. A new ephemeris and determination of oscillation modes of the star based on Fourier analysis are presented. The Two color diagram of the star as a function of its phase is shown. Finally, some of the star's physical parameters including mass, radius and luminosity are calculated.
