Abstract:
We present revised properties for 196468 stars observed by the NASA
Kepler mission and used in the analysis of Quarter 1-16 (Q1-16; May
2009 to Dec 2012) data to detect and characterize transiting planets.
The catalog is based on a compilation of literature values for
atmospheric properties (temperature, surface gravity, and metallicity)
derived from different observational techniques (photometry,
spectroscopy, asteroseismology, and exoplanet transits), which were
then homogeneously fitted to a grid of Dartmouth stellar isochrones.
We use broadband photometry and asteroseismology to characterize 11532
Kepler targets which were previously unclassified in the Kepler Input
Catalog (KIC). We report the detection of oscillations in 2762 of
these targets, classifying them as giant stars and increasing the
number of known oscillating giant stars observed by Kepler by ∼20% to
a total of ∼15500 stars. Typical uncertainties in derived radii and
masses are ∼40% and ∼20%, respectively, for stars with photometric
constraints only, and 5%-15% and ∼10% for stars based on spectroscopy
and/or asteroseismology, although these uncertainties vary strongly
with spectral type and luminosity class. A comparison with the Q1-Q12
catalog shows a systematic decrease in radii of M dwarfs, while radii
for K dwarfs decrease or increase depending on the Q1-Q12 provenance
(KIC or Yonsei-Yale isochrones). Radii of F-G dwarfs are on average
unchanged, with the exception of newly identified giants. The Q1-Q16
star properties catalog is a first step toward an improved
characterization of all Kepler targets to support planet-occurrence
studies.
