Abstract:
The original Kepler mission has delivered unprecedented high-quality
photometry. 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. First
and foremost, our work can assist in the selection of stellar and
exoplanet host samples regarding CMD and binary populations. We
further complemented our catalog by quantifying the impact that
astrometric differences between Gaia data releases have on CMD
location, assessing the contamination in asteroseismic targets with
properties at odds with Gaia, and identifying stars flagged as
photometrically variable by Gaia. We make our catalog publicly
available as a resource to the community when researching the stars
observed by Kepler.
Description:
In this work, we perform a color-magnitude (CMD) diagram and binary
characterization of the ∼200,000 stars observed by the Kepler mission
using the Gaia DR3 data and complementary data bases. The derived CMD
classifications and binary categories are reported, together with CMD
locations and other properties derived throughout the paper.
