cds-question@unistra.frvariable-starseffective-temperatureinfrared-photometryvisible-astronomyWide-band photometryddo-photometryWe have analyzed Kepler light curves for 849 stars with Teff<=5200K from our Cycle 1 Guest Observer program. We identify six new eclipsing binaries, one of which has an orbital period of 29.91 days and two of which are probably W UMa variables. In addition, we identify a candidate "warm Jupiter" exoplanet. We further examine a subset of 670 sources for variability. Of these objects, 265 stars clearly show periodic variability that we assign to rotation of the low-mass star. At the photometric precision level provided by Kepler, 251 of our objects showed no evidence for variability. We were unable to determine periods for 154 variable objects. We find that 79% of stars with Teff<=5200K are variable. The rotation periods we derive for the periodic variables span the range 0.31days<=Prot<=126.5days. A considerable number of stars with rotation periods similar to the solar value show activity levels that are 100 times higher than the Sun.2012AJ....143....4Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/AJ/142/112 : KIC photometric calibration (Brown+, 2011)J/AJ/141/78 : Low-mass eclipsing binaries in KIC (Coughlin+, 2011)http://keplerEBs.villanova.edu/ : Online Kepler eclipsing binary cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/143/4https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/143/4http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/143/4https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/143/4https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/143/4http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/143/4GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/143/4/table2 (Periodic variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/143/4/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/143/4/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/143/4/table2?GETtext/xml+votable180.050000true285.8138437.682891940.005555555555555556Cone search capability for table J/AJ/143/4/table3 (Long period variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/143/4/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/143/4/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/143/4/table3?GETtext/xml+votable180.050000true290.6504237.743690.005555555555555556Cone search capability for table J/AJ/143/4/table4 (Aperiodic variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/143/4/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/143/4/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/143/4/table4?GETtext/xml+votable180.050000true286.8563238.628791940.005555555555555556Cone search capability for table J/AJ/143/4/table5 (Non-variable objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/143/4/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/143/4/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/143/4/table5?GETtext/xml+votable180.050000true284.8059138.806751110.0055555555555555565/3646 3730 3731 3736 3739 3740 3741 3760 3778 3779 3780 3782 3783 3784 3785 3788 3789 3792 6/14581 14588 14591 14749 14751 14759 14761 14762 14763 14765 14766 14770 14779 14780 14783 14825 14826 14827 14830 14915 14918 14919 14929 14930 14931 14933 14936 14938 14939 14941 14942 14943 14948 14950 14951 14954 14955 14969 14972 14975 15044 15045 15104 15105 15107 15108 15109 15110 15126 15127 15145 15146 15148 15149 15151 15160 15172 15173 15174 15176 15178 152008.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/143/4?format=asciiOpticalInfrareddefaultJ/AJ/143/4/table2Periodic variablesrecnoRecord number assigned by the VizieR team.
