Abstract: We present the identification and photometric analysis of 30 new low mass ratio (LMR) totally eclipsing contact binaries found in Catalina Sky Survey data. The LMR candidates are identified using Fourier coefficients and visual inspection. We perform a detailed scan in the parameter plane of mass-ratio (π‘ž) versus inclination (𝑖) using Phoebe-0.31 scripter to derive the best (π‘ž, 𝑖) pair for the initial models. The relative physical parameters are determined from the final model of each system. A Monte-Carlo… Show more
