Abstract:

The eclipsing binary system UV Piscium, which is a short-period RS Canum Venaticorum-type binary system, was observed at Mt. Laguna Observatory during 1980 using the Stromgren 4-color filter system, and broad and narrow Calcium II K-line filters. A new ephemeris was calculated using only photoelectric times of minima. Four sets of orbital solutions were obtained using the Nelson-Davis-Etzel model giving reliable geometric elements for the system. The orbital separation, radii and masses of the stellar components are given in absolute units based on Poppers spectroscopic masses. The light curves exhibit small distortions in the maxima light levels which vary with phase. The system is composed of two well-detached, main sequence stars with the primary a G2 star and the secondary an early K star. Author
