Scientific paper

Preliminary study of the eclipsing binary AB Cas is presented by using the photometric observational data. The primary component is one of the Delta Sct variables with period of 0.054d, and whether the oscillation is of a radial mode or of a nonradial one is discussed. Two color indices (B-V and U-B) data and the light curve analysis suggest that this binary system is a typical Algol type binary system, in which the primary component is near the ZAMS with about 2.3 solar masses and the secondary one is a subgiant star with about 0.5 solar mass.
