<i>KEPLER</i>ECLIPSING BINARY STARS. II. 2165 ECLIPSING BINARIES IN THE SECOND DATA RELEASE

Abstract

The Kepler Mission provides nearly continuous monitoring of ~156 000 objects\nwith unprecedented photometric precision. Coincident with the first data\nrelease, we presented a catalog of 1879 eclipsing binary systems identified\nwithin the 115 square degree Kepler FOV. Here, we provide an updated catalog\naugmented with the second Kepler data release which increases the baseline\nnearly 4-fold to 125 days. 386 new systems have been added, ephemerides and\nprinciple parameters have been recomputed. We have removed 42 previously\ncataloged systems that are now clearly recognized as short-period pulsating\nvariables and another 58 blended systems where we have determined that the\nKepler target object is not itself the eclipsing binary. A number of\ninteresting objects are identified. We present several exemplary cases: 4 EBs\nthat exhibit extra (tertiary) eclipse events; and 8 systems that show clear\neclipse timing variations indicative of the presence of additional bodies bound\nin the system. We have updated the period and galactic latitude distribution\ndiagrams. With these changes, the total number of identified eclipsing binary\nsystems in the Kepler field-of-view has increased to 2165, 1.4% of the Kepler\ntarget stars.\n
