cds-question@unistra.freclipsing-binary-starsinfrared-photometryWe present observations of a new low-mass, double-lined eclipsing binary system discovered using repeat observations of the celestial equator from the Sloan Digital Sky Survey II. Using near-infrared photometry and optical spectroscopy we have measured the properties of this short-period [P=0.407037(14)days] system and its two components. We find the following parameters for the two components: M_1_=0.272+/-0.020M_{sun}_, R_1_=0.268+/-0.010R_{sun}_, M_2_=0.240+/-0.022M_{sun}_, R_2_=0.248+/-0.0090R_{sun}_, T_1_=3320+/-130K, and T_2_=3300+/-130K. The masses and radii of the two components of this system agree well with theoretical expectations based on models of low-mass stars, within the admittedly large errors.2008ApJ...684..635Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/684/635CatalogResearchIsServedByTAP VizieR generic servicerelated-tohttp://www.sdss.org/drsn1/DRSN1_data_release.html : SDSS-II SN survey homehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/684/635https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/684/635http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/684/635https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/684/635https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/684/635http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/684/635GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/ApJ/684/635/table2NIR photometry of SDSS-MEB-1recnoRecord number assigned by the VizieR team.
