Kepler Field with Gaia DR3

These data have impacted numerous research fields (e.g., asteroseismology and exoplanets), and continue to be an astrophysical goldmine. Because of this, thorough investigations of the ~200000 stars observed by Kepler remain of paramount importance.

In this paper, we present a state-of-the-art characterization of the Kepler targets based on Gaia DR3 data. We placed the stars on the color-magnitude diagram (CMD), accounted for the effects of inter- stellar extinction, and classified targets into several CMD categories (dwarfs, subgiants, red giants, photometric binaries, and others). Additionally, we report various categories of candidate binary systems spanning a range of detection methods, such as renormalised unit weight error, radial velocity variables, Gaia non-single stars, Kepler and Gaia eclipsing binaries from the literature, among others.
