The 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 59,174 targets 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.

HD 148797: A bright F-type star with two moderate-period low-density sub-Jovian planets. Compact multi-planet architectures are common in the Neptunian savanna
HD 148797 hosts two ~40 ME, ~8.3 RE, low-density savanna planets near a 1.619 period ratio whose anti-correlated TTVs yield masses and support compact multi-planet architectures as typical in the savanna.

Refined parameters, formation, and dynamical stability of the wild exoplanet system K2-312=HD 80653
HD 80653c is confirmed as a highly eccentric cold Jupiter (P=871.3 d, e=0.8435, M sin i=5.3 MJup) whose orbit and survival of the inner super-Earth are consistent with planet-planet scattering.

Understanding eccentric temperate giants: an in-depth study of the architecture and stellar obliquity of the TOI-2134 system
Updated analysis of TOI-2134 with new TESS sectors and spectra confirms an inner mini-Neptune and outer eccentric sub-Saturn, measures their masses and radii, and reports a 59 degree obliquity for the outer planet via...

Chemical Abundances of the Bioessential Elements C, O and S, and the Refractory Elements Fe and Ni, in Solar-type Exoplanet-hosting Stars from HARPS North and South
Observational study of 290 exoplanet-host stars finds higher C, O, S, Fe, Ni abundances in giant-planet hosts than small-planet hosts, with C/O ratios, hot/warm differences, and mass correlations that vary by subpopulation.
