Abstract

The analysis of the UBV photoelectric study of the short period RS CVn eclipsing binary, UV Psc, has suggested that the primary is a transit with θ e = 27°, i = 88°5, and k = 0.75. The spectral type and luminosity of the hotter component is estimated to be G4-6V and that of the cooler component to be K0-2V. Absolute dimensions for the components of UV Psc were derived by combining the present analysis with that of the spectroscopic analysis given by Popper. The out-of-eclipse observations have showed large amount of scatter and an investigation of this showed that hotter component could be an intrinsic variable. No periodicity for this variation has been fixed due to lack of sufficient data.
