Title: Photometric Characterization of K2 and TESS Exoplanets with WIYN

Abstract: We propose to use WIYN for confirmation and characterization of exoplanets discovered by NASA's K2 and TESS missions. With WHIRC we will obtain high-precision, high-cadence, high-spatial-resolution near- infrared transit photometry of exoplanets and candidates. This will enable new measurements of the transit ephemerides, which is necessary due to the relatively short timescale of K2 and TESS observations for a majority of stars. We will also verify the planet host stars, which is necessary in crowded fields, and we will use the transit color (optical from K2 and TESS versus near-infrared from WIYN) to determine whether candidates have a planetary nature or are instead false positives due to a stellar blend. With NESSI we will obtain very-high-spatial-resolution speckle images to complement our ongoing transit survey, which will allow us to identify close-in stellar companions to planet host stars and account for the blended light in our analysis of the transit light curves. These WIYN observations will ultimately contribute to a catalog of well-characterized K2 and TESS planets that could be prime targets for atmospheric characterization with JWST.
