Abstract:
The primary Kepler Mission provided nearly continuous monitoring of
∼200000 objects with unprecedented photometric precision. We present
the final catalog of eclipsing binary systems within the 105deg2
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
https://keplerEBs.villanova.edu/.
Description:
The Kepler Eclipsing Binary Catalog lists the stellar parameters from
the Kepler Input Catalog (KIC) augmented by: primary and secondary
eclipse depth, eclipse width, separation of eclipse, ephemeris,
morphological classification parameter, and principal parameters
determined by geometric analysis of the phased light curve.
The previous release of the Catalog (Paper II; Slawson et al. 2011,
cat. J/AJ/142/160) contained 2165 objects, through the second Kepler
data release (Q0-Q2). In this release, 2878 objects are identified and
analyzed from the entire data set of the primary Kepler mission
(Q0-Q17). The online version of the Catalog is currently maintained at
https://keplerEBs.villanova.edu/. A static version of the online
Catalog associated with this paper is maintained at MAST
https://archive.stsci.edu/kepler/eclipsing_binaries.html.

hemispheres of two stars in the binary system. These systems are flagged
with the "REF" flag in the Catalog. See additional details in Section 8.2.
Note (2): Those reported without BJD0 errors are also heartbeat stars.

Note (1): Sources with additional features (see Section 8.4) can be another sign
of a stellar triple or multiple system. In this case the depth of the event
is too deep to be the transit of a planet but is instead an eclipse by, or
occultation of a third stellar body. We have been looking for such features
in the Catalog and have uncovered 14 systems exhibiting multiple,
determinable periods. These systems are flagged with the "M" flag in the
Catalog.

Note (1): In some systems, extraneous events are observed whose ephemerides
cannot be determined. In some cases the period is longer than the time
baseline and two subsequent events have not been observed by Kepler. In
other cases, eclipsing the inner-binary at different phases results in a
nonlinear ephemeris with an indeterminable period. It is worth noting that
without spectroscopy or Eclipse Timing Variations (ETVs) that are in
agreement that additional eclipse event is indeed related, these cases are
not guaranteed to be multiple objects-some could be the blend of two
independent binaries on the same pixel.
