Abstract
ABSTRACT Photoelectric BV light curves of the close binary system BO Peg (P = 0d.580) are obtained and analyzed with a synthesis method to determine the photometric elements. It is found that the components of BO Peg are not in contact with each other but almost fill their respective Roche lobes. Two spectrograms of the system (A7 IV-V) have also been obtained, and a brief discussion on physical quantities of the components is made.
