摘要：An accurate and precise Kepler Stellar Properties Catalog is essential for the interpretation of the Kepler exoplanet survey results.Previous Kepler Stellar Properties Catalogs have focused on reporting the best-available parameters for each star, but this has required combining data from a variety of heterogeneous sources.We present the Gaia–Kepler Stellar Properties Catalog, a set of stellar properties of 186,301 Kepler stars, homogeneously derived from isochrones and broadband photometry, Gaia Data Release 2 parallaxes, and spectroscopic metallicities, where available.Our photometric effective temperatures, derived from $g\,\mathrm{to}\,{K}_{s}$ colors, are calibrated on stars with interferometric angular diameters.Median catalog uncertainties are 112 K for ${T}_{\mathrm{eff}}$, 0.05 dex for $\mathrm{log}\,g$, 4% for ${R}_{\star }$, 7% for ${M}_{\star }$, 13% for ${\rho }_{\star }$, 10% for ${L}_{\star }$, and 56% for stellar age.These precise constraints on stellar properties for this sample of stars will allow unprecedented investigations into trends in stellar and exoplanet properties as a function of stellar mass and age.In addition, our homogeneous parameter determinations will permit more accurate calculations of planet occurrence and trends with stellar properties.
