Kepler Eclipsing Binary Stars. Vii. The Catalog of Eclipsing Binaries Found in the Entire Kepler Data Set

Abstract

The primary Kepler Mission provided nearly continuous monitoring of ∼200,000 objects with unprecedented photometric precision. We present the final catalog of eclipsing binary systems within the 105 deg 2 Kepler field of view. This release incorporates the full extent of the data from the primary mission (Q0-Q17 Data Release). As a result, new systems have been added, additional false positives have been removed, ephemerides and principal parameters have been recomputed, classifications have been revised to rely on analytical models, and eclipse timing variations have been computed for each system. We identify several classes of systems including those that exhibit tertiary eclipse events, systems that show clear evidence of additional bodies, heartbeat systems, systems with changing eclipse depths, and systems exhibiting only one eclipse event over the duration of the mission. We have updated the period and galactic latitude distribution diagrams and included a catalog completeness evaluation. The total number of identified eclipsing and ellipsoidal binary systems in the Kepler field of view has increased to 2878, 1.3% of all observed Kepler targets. An online version of this catalog with downloadable content and visualization tools is maintained at http://keplerEBs.villanova.edu.

Radial Velocity Monitoring of Kepler Heartbeat Stars*

“…We have selected our targets from the list of 173 known Kepler HB stars, all flagged with the "HB" flag in the Kepler eclipsing binary (EB) online catalog 12 Slawson et al 2011;Kirk et al 2016). Although HB systems do not necessarily show eclipses they do show a drop and/or rise in flux during periastron passage which is reminiscent of an eclipse, or an inverted eclipse.…”

“…The access to a relatively large number of nights while Notes. a Photometric period, taken from the Kepler EB catalog (Kirk et al 2016). b Photometric amplitude of the heartbeat signal at periastron, defined as the full flux variation, in ppm, of the phase folded and binned light curve (see Appendix B).…”

“…The initial T 0 position was arbitrarily set, taken to be the predicted time of eclipse, based on the eclipse ephemeris listed in the Kepler EB catalog (Kirk et al 2016), which was closest to the middle of the time period covered by the RV measurements. For non-eclipsing systems the Kepler EB catalog reports the time of minimum flux, although that distinction is not important since we are using this time only as an arbitrary starting point for T 0 .…”

“…Since the first discoveries of HB stars in Kepler data Thompson et al 2012) the number of known HB stars has substantially increased and is currently at 173 (Kirk et al 2016). However, the Kepler light curves alone are not sufficient for taking advantage of the scientific opportunities HB stars offer.…”

Planetary Candidates Observed by Kepler. VIII. A Fully Automated Catalog with Measured Completeness and Reliability Based on Data Release 25

“…Studying stars in clusters enabled Meibom et al (2011) to map out the evolution of stellar rotation as stars age. Kepler also produced light curves of 2876 38 eclipsing binary stars Kirk et al 2016), including unusual binary systems, such as the eccentric, tidally distorted, Heartbeat stars Thompson et al 2012;Shporer et al 2016) that have opened the doors to understanding the impact of tidal forces on stellar pulsations and evolution (e.g., Fuller et al 2017;Hambleton et al 2017).…”
