Apsidal Motion of Stars
Abstract
The photoelectric light curves of the eclipsing binaries YY Sagittarii and RS Canum Venaticorum are presented. It is found that the orbital eccentricity of YY Sgr is greater than 0.15, and may be considerably larger. The primary minimum of Rs CVn is asymmetrical near the shoulders, and the maxima are of unequal height. It is suggested that streams of gas may be presented in this system and contribute to the asymmetry of the minima. The length of the period of primary minimum appears to vary in a 35 year cycle. The secondary minimum may at present be slightly displaced in the direction to be expected if the variation in primary period is the result of apsidal motion.
