Scientific paper

An analysis of UBVR light variations of AD Canis Minoris (CMi) is presented. The mean effective temperature derived from the intrinsic (B - V) index is estimated to be 7400 K +/- 100 K whereas that of the (V - R) index value is 8425 K +/- 120 K. The mean variation of temperature from the (B - V) index over a pulsation cycle is almost twice that of the estimated (V - R) index value. The estimated mass, radius and effective gravity values suggest that AD CMi is a normal population-I pulsating star and a member of the delta-Scuti group.
