CSS detached eclipsing binaries

In the era of all-sky surveys, thousands of eclipsing binaries have been charted, yet their light curves remain unexplored. The goal of this work is to use time series and colour information to extract physical parameters of the binary systems when the spectroscopic information is not available.

Inspired by the work of Devor et al., we use the Detached Eclipsing Binary Light curve fitter (DEBiL) and the Method for Eclipsing Component Identification (MECI) to derive basic properties of the binary systems identified by the Catalina Sky Surveys. We derive the mass, fractional radius, and age for 2170 binary systems. We report 211 eccentric systems and compare their properties to the tidal circularization theory.
