cds-question@unistra.freclipsing-binary-starsastronomical-modelsproper-motionsapparent-magnitudeIn recent years, we have witnessed an explosion of photometric time-series data, collected for the purpose of finding a small number of rare sources, such as transiting extrasolar planets and gravitational microlenses. Once combed, these data are often set aside, and are not further searched for the many other variable sources that they undoubtedly contain. To this end, we describe a pipeline that is designed to systematically analyze such data, while requiring minimal user interaction. We ran our pipeline on a subset of the Trans-Atlantic Exoplanet Survey dataset, and used it to identify and model 773 eclipsing binary systems. For each system we conducted a joint analysis of its light curve, colors, and theoretical isochrones. This analysis provided us with estimates of the binary's absolute physical properties, including the masses and ages of their stellar components, as well as their physical separations and distances. We identified three types of eclipsing binaries that are of particular interest and merit further observations. The first category includes 11 low-mass candidates, which may assist current efforts to explain the discrepancies between the observation and the models of stars at the bottom of the main sequence. The other two categories include 34 binaries with eccentric orbits, and 20 binaries with abnormal light curves. Finally, this uniform catalog enabled us to identify a number of relations that provide further constraints on binary population models and tidal circularization theory.2008AJ....135..850Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/850CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2010)B/vsx : AAVSO International Variable Star Index VSX (Watson+, 2006-2010)V/115 : Semi-detached eclipsing binaries (Surkova+, 2004)V/118 : Catalog of eclipsing binaries parameters (Perevozkina+, 1999)V/119 : Catalogue of field contact binary stars (Pribulla+, 2003)V/120 : Catalog of early-type contact binaries (Bondarenko+, 1996)V/124 : Approximate elements of eclipsing binaries (Svechnikov+, 1990)V/121 : Catalog of DMS-type eclipsing binaries (Svechnikov+, 1999)J/A+A/337/403 : Low-mass stars evolutionary models (Baraffe+ 1998)http://www.cfa.harvard.edu/~jdevor/Catalog.html : online author's cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/850https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/850http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/850https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/850https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/850http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/850GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/850/table7 (Eclipsing Binary catalog (773 stars))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/850/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/850/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/850/table7?GETtext/xml+votable180.050000true20.053448.611488890.005555555555555556Cone search capability for table J/AJ/135/850/table9 (EBs that appear in either the VSX or the SIMBAD astronomical databases)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/850/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/850/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/850/table9?GETtext/xml+votable180.050000true20.053448.611488890.005555555555555556Cone search capability for table J/AJ/135/850/table1 (Observational parameters of the TrES fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/850/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/850/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/850/table1?GETtext/xml+votable180.050000true17.37552305647.24179250.0055555555555555564/178 5/267 390 393 395 396 671 694 716 736 737 738 2533 2540 2541 3702 3705 3706 3707 3708 3709 3743 3784 3785 3786 6/1063 1067 1072 1080 1082 1083 1084 1152 1153 1156 1157 1158 1164 1165 1167 1168 1169 1170 1172 1173 1174 1176 1177 1178 1551 1554 1566 1576 1579 1589 1590 1593 1594 1595 1596 1597 1598 1634 1668 1669 1671 1680 1681 1682 1684 2677 2678 2679 2681 2682 2765 2766 2767 2770 2771 2772 2773 2775 2781 2782 2783 2789 2800 2801 2804 2805 2807 2825 2826 2827 2829 2830 2831 2842 2843 2846 2847 2960 2976 5879 5881 5883 5886 5887 6050 6057 6058 7237 7248 7250 7252 7253 7257 7258 7281 7425 7432 9370 9371 9383 9387 9389 9395 9398 9401 9403 9404 9405 9407 9450 9646 9647 9650 9651 9657 9658 9660 9744 9745 9748 9750 9752 9753 9985 9988 9991 9993 9995 9996 9998 10000 10002 10003 10006 10008 10010 10012 10022 10023 10032 10138 10139 10140 10141 10143 10168 10169 10174 10176 10178 10185 10208 10209 10210 11537 11538 14799 14814 14819 14841 14842 14843 14844 14845 14846 14943 14959 14963 14965 14966 14967 14969 14970 14971 15045 15056 15057 15060 15061 15114 15115 15118 15148 15149 15150 15152 15153 15154 15172 15173 15184 15185 15187 15232 155208.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/850?format=asciidefaultJ/AJ/135/850/table7Eclipsing Binary catalog (773 stars)recnoRecord number assigned by the VizieR team.
