Abstract
The first multicolor observations and light curve solutions of the stars 1SWASPÂ J130111.22+420214.0 and 1SWASPÂ J231839.72+352848.2 are presented. The estimated physical parameters of 1SWASPÂ J130111.22+420214.0 are M1=1.0Mâ,M2=1.63Mâ,R1=0.77Râ,R2=0.91Râ,L1=0.59Lâ, and L2=0.68Lâ. While a binary model could not be fitted to the light curve of 1SWASPÂ J231839.72+352848.2, its Fourier series representation indicates that this system could well be a rotating ellipsoidal variable. The components of 1SWASPÂ 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.
