cds-question@unistra.fropen-star-clustersvariable-starseclipsing-binary-starsWe have conducted a deep (15~<r~<23 ), 20 night survey for transiting planets in the intermediate-age (~550Myr) open cluster M37 (NGC 2099) using the Megacam wide-field mosaic CCD camera on the 6.5m MMT. In this paper we present a catalog and light curves for 1445 variable stars; 1430 (99%) of these are new discoveries. We have discovered 20 new eclipsing binaries and 31 new short-period (P<1day) pulsating stars. The bulk of the variables are most likely rapidly rotating young low-mass stars, including a substantial number (>~500) that are members of the cluster. We identify and analyze five particularly interesting individual variables, including a previously identified variable that we suggest is probably a hybrid gamma Doradus/delta Scuti pulsator, two possible quiescent cataclysmic variables, a detached eclipsing binary (DEB) with at least one gamma Doradus pulsating component (only the second such variable found in an eclipsing binary), and a low-mass (M_P_~M_S~0.6M_{sun}_ DEB that is a possible cluster member. A preliminary determination of the physical parameters for the DEB+gamma Doradus system yields M_P_=1.58+/-0.04M_{sun}_, M_S_=1.58+/-0.04M_{sun}_, R_P_=1.39+/-0.07R_{sun}_, and R_S_=1.38+/-0.07R_{sun}_.2008ApJ...675.1254Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/675/1254CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/381/65 : BVI photometry of NGC 2099 (Nilakshi+, 2002)J/A+A/412/721 : CCD {Delta}a-photometry of 5 open clusters (Paunzen+, 2003)J/A+A/483/253 : BV photometry of NGC 2099 variables (Messina+, 2008)J/ApJ/675/1233 : gri photometry in M37 (NGC 2099) (Hartman+, 2008)J/ApJ/691/342 : griBVI photometry in M37 (Hartman+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/675/1254https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/675/1254http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/675/1254https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/675/1254https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/675/1254http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/675/1254GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/675/1254/m37var (Variables and suspected variables in M37)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/675/1254/m37var?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/675/1254/m37var?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/675/1254/m37var?GETtext/xml+votable180.050000true88.084791732.55566670.0055555555555555566/24520 24522https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/675/1254?format=asciiOpticaldefaultJ/ApJ/675/1254/m37varVariables and suspected variables in M37recnoRecord number assigned by the VizieR team.
