Photoelectric observations of W UMa stars: U Pegasi and AB Andromedae.
Abstract
Recent photoelectric-photometric data of the W UMa systems U Pegasi and AB Andromedae are reported. From the times of minima found in the literature and those obtained in the present paper, quadratic ephemerides were calculated.
