Observations of six southern eclipsing binaries for apsidal motion.
Abstract
Photoelectric UBV observations are presented for the six eclipsing binaries KX Pup, EO Vel, HH Car, AY Mus, KT Cen, and GM Nor. Photometric elements are determined together with rough estimates of masses and radii. KX Pup, EO Vel, KT Cen, and GM Nor are found to exhibit apsidal motion in good agreement with theory. HH Car, for which apsidal motion was previously reported, has a circular orbit and shows a distorted light curve due to circumstellar matter. AY Mus has stopped eclipsing, apparently because of perturbations by a third body in the system.
