cds-question@unistra.freclipsing-binary-starsm-starsstellar-massesinfrared-photometryvisible-astronomyphotometryWe present the discovery and characterization of six new M dwarf eclipsing binary systems. The 12 stars in these eclipsing systems have masses spanning 0.38-0.59M_{sun}_ and orbital periods of 0.6-1.7 days, with typical uncertainties of ~0.3% in mass and ~0.5%-2.0% in radius. Combined with six known systems with high-precision measurements, our results reveal an intriguing trend in the low-mass regime. For stars with M=0.35-0.80M_{sun}_, components in short-period binary systems (P<~1 day; 12 stars) have radii which are inflated by up to 10% ({mu}=4.8+/-1.0%) with respect to evolutionary models for low-mass main-sequence stars, whereas components in longer-period systems (>1.5 days; 12 stars) tend to have smaller radii ({mu}=1.7+/-0.7%).2011ApJ...728...48Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/728/48CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2012)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/A+A/526/A29 : ASAS low-mass EB* light curves (Helminiak+, 2011)J/AJ/141/78 : Low-mass eclipsing binaries in KIC (Coughlin+, 2011)J/ApJ/684/635 : New low-mass eclipsing binary from SDSS-II (Blake+, 2008)J/AJ/134/2340 : Membership of Praesepe and Coma Berenices (Kraus+, 2007)J/AJ/134/1488 : MG1 Variable Star Catalog (MG1-VSC) (Kraus+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/728/48https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/728/48http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/728/48https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/728/48https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/728/48http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/728/48GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/728/48/table1 (New M-dwarf eclipsing binaries)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/728/48/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/728/48/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/728/48/table1?GETtext/xml+votable180.050000true51.586253.210.0055555555555555566/18895 22289 22971 23229 27405 301588.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/728/48?format=asciiOpticalInfrareddefaultJ/ApJ/728/48/table1New M-dwarf eclipsing binariesrecnoRecord number assigned by the VizieR team.
