Abstract
ABSTRACT Ha and H photoelectric observations of 33 early-type standard stars and 23 Be stars were obtained at the Villanova University Observatory on 27 nights between January 1972 and February 1973. The data permit separation of the stronger-lined Be stars from the normal stars and reveal variations in the Be star Cas. When compared with earlier data obtained by others, the Villanova data show longer-term variations in five other Be stars as well: w Ori, Tau, K Dra, 23 Tau, and Per. Key words: Be stars - emission - narrow-band photometry
