Title: Characterizing K2 Exoplanets with High-Precision Near-Infrared Transit Photometry

Abstract: We propose to use WIYN+WHIRC to obtain high-precision, high-cadence, near-infrared transit photometry of exoplanets and candidates discovered by the NASA K2 mission. We will specifically take advantage of the opportunity for simultaneous optical observations with the Kepler spacecraft to observe both young and old exoplanets and probe stellar activity. These observations will ultimately support the confirmation and characterization of K2 exoplanets, many of which are in the super- Earth-size regime and orbit cool, nearby stars. We will improve measurements of each planet's orbit and size thanks to minimization of stellar limb darkening in the near-infrared. For candidate planets, we will use the transit color (optical from K2 versus near-infrared from WIYN) to determine whether the candidates have a planetary nature or are instead false positives (e.g., background eclipsing binaries or hierarchical triple systems). These observations will contribute to the creation of a catalog of well-characterized K2 planets around young stars and cool, nearby stars that will be prime targets for atmospheric characterization with JWST.
