Abstract
We report observations of a deep near-ultraviolet (NUV) survey of the
Kepler field made in 2012 with the Galaxy Evolution Explorer (GALEX)
Complete All-Sky UV Survey Extension (CAUSE). The GALEX-CAUSE Kepler
survey (GCK) covers 104 square degrees of the Kepler field and reaches a
limiting magnitude of NUV ≃ 22.6 at 3σ. Analysis of the GCK
survey has yielded a catalog of 669,928 NUV sources, of which 475,164
are cross-matched with stars in the Kepler Input Catalog. Approximately
327 of 451 confirmed exoplanet host stars and 2614 of 4696 candidate
exoplanet host stars identified by Kepler have NUV photometry in the GCK
survey. The GCK catalog should enable the identification and
characterization of UV-excess stars in the Kepler field (young
solar-type and low-mass stars, chromospherically active binaries, white
dwarfs, horizontal branch stars, etc.), and elucidation of various
astrophysics problems related to the stars and planetary systems in the
Kepler field.
