Abstract:We have identified and photometrically characterized a sample of 230 detached close-orbiting eclipsing binaries with low-mass main-sequence components (LMMS) from the Catalina Sky Survey. These low-mass stars have both components below 1.0M_{sun}_, orbital periods shorter than 2-days and effective temperatures below to 5720K. The adopted method provided a robust estimate of stellar parameters (as mass and fractional radius) by using only light curves and photometric colors, since no spectroscopic information was available for these objects. Each light curve was modeled with the JKTEBOP code together with an asexual genetic algorithm to obtain the most coherent values for the fitted parameters. This new sample of short-period detached eclipsing ...(more)
Abstract: (hide)
We present the orbital and physical parameters for our complete sample of 230 detached EBs found in the Catalina Sky Survey. The derived effective temperatures and masses for the individuals components were obtained from a grid of composite synthetic and observed colors, as described in detail in sect. 3 of the paper. The orbital parameters and fractional radii, were obtained from the light curve modeling as described in sect. 4 of the paper. The last two columns show the radii obtained by using Kepler's third law.
