cds-question@unistra.freclipsing-binary-starslate-type-starsphotometryeffective-temperaturestellar-massesstellar-radiiWe 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 binaries, with low-mass main-sequence stars (LMMS) considerably increases the number of previously known systems. Which allows us to derive masses and radii in statistically significant samples for the investigation of the correlation between radius inflation and other basic stellar parameters.2019MNRAS.482.5379Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/482/5379CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/469/3688 : CSS Periodic Variable Star Catalogue (Drake+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/482/5379https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/482/5379http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/482/5379https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/482/5379https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/482/5379http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/482/5379GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/482/5379/tablea1Orbital and physical parameters for our complete 230 detached EBs identified in the Catalina Sky SurveyeEccentricitysrc.orbital.eccentricityfloatwLongitude of periastrondegsrc.orbital.periastronfloate_w?
