Abstract

(Abstract only) A complete light curve of the eclipsing binary UZ Sge has been determined in V and R bands. Four new times of minimum are reported (two for primary eclipse and two for secondary eclipse), which verify other recent O–C observations. The color index changes significantly during both primary eclipse and secondary eclipse, providing some constraints on the stars’ temperatures. binarymaker3 software has been used to compare the observed Vand R light curves with two models of this system (with quite different mass ratios of q = 0.14 and q = 0.68, respectively) that have been suggested in the literature.
