Period study of the short period RS CVn type eclipsing binary UV Piscium

Abstract

The short period RS CVn type eclipsing binary UV Piscium was observed photoelectrically with standard U, B, V filters for three consecutive observing seasons during 1976-1979. A total of nine primary minima in each of V and B colours and seven primary minima in U colour were obtained. All these minima and those obtained by Carr, Oliver, and Sadik were corrected for the distortion wave superposed on the light curves. Using these wave-corrected times of minima the following improved light elements were derived : Hel. JD 2443080.1843 + 0/sopd/. 8610474 E. The (O -C)s obtained using these ephemeris suggest no earlier suggestions of period variation in this system.
