Photometric variability of LBV-candidate stars and Hubble-Sandage variables A, B, C and 2 in M 33.

KURTEV R.G., CORRAL L.J. and GEORGIEV L.

Abstract (from CDS):

We present the photometric history of some Luminous Blue Variable candidate stars in M 33. The search for outbursts was made in photographic plates taken in the B band of the galaxy M 33 and cover an eight year period, 1982-1990. Twenty five plates, separated into seven groups, have been used. CCD UBV magnitudes of the star UIT 003 are presented also. Only one (of 12) of the LBV candidates (UIT 003) presents clear variability above the noise. The combination of photometric variability and a typical LBV spectrum make it a new LBV. We present also the light curves of Hubble-Sandage Variables A, B, C and 2.
