Abstract
This study presents the photometric solutions of six binary systems with circular orbits and low mass components. Solutions for the sum of radii fraction, radii ratio, orbital inclination, surface brightness ratio, orbital eccentricity parameters were obtained, as well as a new solution for the orbital period, using data from V-band photometry from the All-Sky Automated Survey for Supernovae. Based on the geometry of the light curve, the study samples were analyzed using JKTEBOP code. In addition, their global parameters were also estimated, by applying based calibrations for the late main-sequence stars and color index (J-K). Thus, mass, temperature, luminosity, and radius values for each stellar component are also provided.
