Abstract: | A total of 185 luminous blue variable star (LBV) candidates with V<18·m 5 are selected based on the results of aperture photometry. The primary selection criterion is that the prospective candidate
should be a blue star with Hα emission. In order not to overlook appreciably reddened LBV candidates, we compose an additional list of 25 red (0·m35< B − V < 1·m2, V < 18·m5) emission star candidates. A comparison with the list of known variables in the M33 galaxy showed 29% of our selected candidates
to be photometrically variable. We also find our list to agree well with the lists of emission-line objects obtained in earlier
papers using different methods. |
