uvby - β Photoelectric Photometry of the Open Cluster α Per

Abstract

Absolute photoelectric photometry of stars in the direction of the Open Cluster α Per has been secured and is presented along with an analysis reinforced with all the available data in Strömgren uvby-β photometry compiled from the literature. Cluster membership is analyzed and the physical characteristics of the stars have been deduced. The membership determined in this paper is compared with that of proper motion studies and Hipparcos.
