Abstract:
The determination of exoplanet properties and occurrence rates using
Kepler data critically depends on our knowledge of the fundamental
properties (such as temperature, radius, and mass) of the observed
stars. We present revised stellar properties for 197096 Kepler targets
observed between Quarters 1-17 (Q1-17), which were used for the final
transiting planet search run by the Kepler Mission (Data Release 25,
DR25). Similar to the Q1-16 catalog by Huber+ (2014, J/ApJS/211/2),
the classifications are based on conditioning published atmospheric
parameters on a grid of Dartmouth isochrones, with significant
improvements in the adopted method and over 29000 new sources for
temperatures, surface gravities, or metallicities. In addition to
fundamental stellar properties, the new catalog also includes
distances and extinctions, and we provide posterior samples for each
stellar parameter of each star. Typical uncertainties are ∼27% in
radius, ∼17% in mass, and ∼51% in density, which is somewhat smaller
than previous catalogs because of the larger number of improved logg
constraints and the inclusion of isochrone weighting when deriving
stellar posterior distributions. On average, the catalog includes a
significantly larger number of evolved solar-type stars, with an
increase of 43.5% in the number of subgiants. We discuss the overall
changes of radii and masses of Kepler targets as a function of
spectral type, with a particular focus on exoplanet host stars.
