cds-question@unistra.freclipsing-binary-starssolar-system-planetsapparent-magnitudeThe original Kepler mission observed and characterized over 2400 eclipsing binaries (EBs) in addition to its prolific exoplanet detections. Despite the mechanical malfunction and subsequent non-recovery of two reaction wheels used to stabilize the instrument, the Kepler satellite continues collecting data in its repurposed K2 mission surveying a series of fields along the ecliptic plane. Here, we present an analysis of the first full baseline K2 data release: the Campaign 0 data set. In the 7761 light curves we have identified a total of 207 EBs. Of these, 97 are new discoveries that were not previously identified. Our pixel-level analysis of these objects has also resulted in identification of several false positives (observed targets contaminated by neighbouring EBs), as well as the serendipitous discovery of two short-period exoplanet candidates. We provide catalogue cross-matched source identifications, orbital periods, morphologies and ephemerides for these eclipsing systems. We also describe the incorporation of the K2 sample into the Kepler Eclipsing Binary Catalog, present spectroscopic follow-up observations for a limited selection of nine systems and discuss prospects for upcoming K2 campaigns.2015MNRAS.452.3561Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/452/3561CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/A+A/579/A19 : K2 Variable Catalogue (Armstrong+, 2015)J/MNRAS/456/2260 : K2 Variability Catalogue II (Armstrong+, 2016)J/AJ/141/83 : Eclipsing binaries in Kepler first data release (Prsa+ 2011)J/AJ/142/160 : Kepler Mission.
