cds-question@unistra.frmultiple-starssolar-system-planetsstellar-radiiradial-velocitychemical-abundancesThe Kepler Space Telescope is currently searching for planets transiting stars along the ecliptic plane as part of its extended K2 mission. We processed the publicly released data from the first year of K2 observations (Campaigns 0, 1, 2, and 3) and searched for periodic eclipse signals consistent with planetary transits. Out of the 59174 targets that we searched, we detect 234 planetary candidates around 208 stars. These candidates range in size from gas giants to smaller than the Earth, and range in orbital periods from hours to over a month. We conducted initial reconnaissance spectroscopy of 68 of the brighter candidate host stars, and present high-resolution optical spectra for these stars. We make all of our data products, including light curves, spectra, and vetting diagnostics available to users online.2016ApJS..222...14Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/222/14CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)J/MNRAS/456/2260 : K2 Variability Catalogue II (Armstrong+, 2016)J/A+A/582/A33 : K2-19b light curve (Armstrong+, 2015)J/A+A/579/A19 : K2 Variable Catalogue (Armstrong+, 2015)J/ApJ/810/95 : Kepler pipeline S/N studies.
