Light and colour curve observations and analysis of the short period eclipsing binary system UV PSC
In the present work B and V light curves and the (B-V)-color curve ofthe short period (RS CVn type) binary system UV Psc are presented andanalyzed, and absolute information from the available data are derived.Chi-squared minimization procedures were utilized to a large extent infitting light and color curves. The solutions show the binary to be at adistance of about 90 pc with two detached components which are close tothe main sequence (G2 and K0). The inclination of the orbit is close to90 deg. Photometric irregularities present in the light curve arebriefly considered in relation to current ideas on RS CVn systems, andthe color information indicates that a locally hotter (rather thancooler) region is responsible for the irregularities.
