cds-question@unistra.frmultiple-starseclipsing-binary-starsinfrared-photometryvisible-astronomyphotometrystellar-massesstellar-radiieffective-temperatureNew CCD photometric observations of fourteen short-period low-mass eclipsing binaries (LMBs) in the photometric filters I, R, and V were used for a light curve analysis. A discrepancy remains between observed radii and those derived from the theoretical modeling for LMBs, in general. Mass calibration of all observed LMBs was performed using only the photometric indices. The light curve modeling of these selected systems was completed, yielding the new derived masses and radii for both components. We compared these systems with the compilation of other known double-lined LMB systems with uncertainties of masses and radii less then 5%, which includes 66 components of binaries where both spectroscopy and photometry were combined together. All of our systems are circular short-period binaries, and for some of them, the photospheric spots were also used. A purely photometric study of the light curves without spectroscopy seems unable to achieve high enough precision and accuracy in the masses and radii to act as meaningful test of the M-R relation for low-mass stars.2017AJ....154...30Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/A+A/398/239 : RI differential photometry of CU Cnc (Ribas, 2003)J/AJ/130/2838 : Velocity and light curves of RW Lac (Lacy+, 2005)J/ApJ/640/1018 : Differential photometry of V1061 Cyg (Torres+, 2006)J/AJ/136/1067 : New beta Lyrae and Algol candidates in NSVSJ/ApJ/684/635 : New low-mass eclipsing binary from SDSS-II (Blake+, 2008)J/ApJ/691/1400 : Absolute properties of CM Dra (Morales+, 2009)J/ApJ/707/671 : IM Vir BVRI photometry and radial velocitiesJ/other/A+ARV/18.67 : Accurate masses and radii of normal stars (Torres+, 2010)J/A+A/526/A29 : ASAS low-mass eclipsing binaries light curvesJ/AJ/141/78 : Low-mass eclipsing binaries in KIC (Coughlin+, 2011)J/AJ/141/166 : HATNet variability survey of K and M dwarfsJ/ApJ/728/48 : Multicolor eclipse data for 6 new binaries (Kraus+, 2011)J/ApJ/742/123 : Photometry and Velocity of LSPM J1112+7626 (Irwin+, 2011)J/AJ/145/16 : Differential BVRI light curves of NSVS 02502726J/ApJS/208/9 : Intrinsic colors and temperatures of PMS starshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/30https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/30/table7 (Parameters of double-lined low-mass binary components for which uncertainties of masses and radii are less than 5%)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/30/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/30/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/30/table7?GETtext/xml+votable180.050000true35.211878133.34654220.005555555555555556Cone search capability for table J/AJ/154/30/table2 (Basic properties of systems from Hoffman et al.
