Abstract

The results are presented from analysis of 16 high-and medium-dispersion spectrograms of the system. Mass loss from the primary has a strong dependence on phase in an orbit of low eccentricity. No change in period is detected but the primary star amplitude shows an ~ 10% increase over the value derived from observations in 1957. The secondary spectrum is described and the fundamental parameters of the stars and their evolutionary status are discussed.
