Abstract
The first multicolor observations and light curve solutions of the stars 1SWASP J130111.22+420214.0 and 1SWASP J231839.72+352848.2 are presented. The estimated physical parameters of 1SWASP J130111.22+420214.0 are M1=1.0M⊙,M2=1.63M⊙,R1=0.77R⊙,R2=0.91R⊙,L1=0.59L⊙, and L2=0.68L⊙. While a binary model could not be fitted to the light curve of 1SWASP J231839.72+352848.2, its Fourier series representation indicates that this system could well be a rotating ellipsoidal variable. The components of 1SWASP J130111.22+420214.0 are also compared to other well–known binary systems and their position in mass–radius plane and the Hertzsprung–Russel diagram are argued and possible evolutionary statuses are discussed.
