title: Parameter catlogs of "Photometric Stellar Parameters for 195,478 KIC Stars"

description: Data Abstract

Here are the parameter catalogs of KIC (Kepler Input Catalog) stars from the paper "Photometric Stellar Parameters for 195,478 KIC Stars." The paper includes two separate catalogs: one for A, F, G, and K type stars, and another for M type stars. Please note that the reliability of M-type star parameters is lower compared to that of AFGK stars, and caution is advised when using these values for further analysis. For this reason, we do not provide isochrone-fitting parameters for M-type stars. For detailed information on each catalog, please refer to the "Catalog Description" section. Each catalog is available in both FITS and CSV formats, with identical data content across these formats.

Article Abstract

The stellar atmospheric parameters and physical properties of stars in the Kepler Input Catalog (KIC) are of great significance for the study of exoplanets, stellar activity, and asteroseismology. However, despite extensive effort over the past decades, accurate spectroscopic estimates of these parameters are available for only about half of the stars in the full KIC catalog. In our work, by training relationships between photometric colors and spectroscopic stellar parameters from Gaia DR3, the Kepler Issac-Newton Survey, LAMOST DR10, and APOGEE DR17, we have obtained atmospheric-parameter estimates for over 195,000 stars, accounting for 97$\%$ of the total sample of KIC stars. We obtain 1$\sigma$ uncertainties of 0.1\,dex on metallicity [Fe/H], 100\,K on effective temperature $T_{\rm eff}$, and 0.2\,dex on surface gravity log $g$. In addition, based on these atmospheric parameters, we estimated the ages, masses, radii, and surface gravities of these stars using the commonly adopted isochrone-fitting approach. The resulting precision for turn-off stars is 20$\%$ in age; for dwarf stars, it is 0.07 $M_{\odot}$ in mass, 0.05 $R_{\odot}$ in radius, and 0.12 dex in surface gravity; and for giant stars, it is 0.14 $M_{\odot}$ in mass, 0.73 $R_{\odot}$ in radius, and 0.11 dex in surface gravity.

Notes of the Data

Please note the following two points:





The A, F, G and K-type star parameter table contains the complete rows of KIC, with a total of 200,038 rows. The M-type star table includes the stars that have been filtered with $(BP-RP)_0$ > 1.8.






The total number of stars with parameter measurements is determined as follows:

1) For A-, F-, G-, and K-type stars, we include those with metallicity measurements derived from either photometric data synthesized from Gaia XP spectra or KIS photometry, resulting in a total of 190,226 stars.

2) For M-type stars, only 5,252 stars with metallicity measurements based on Gaia XP spectra are considered, as the UV radiation of M-type stars is weak, making KIS-based measurements unreliable. Although these KIS-derived values are listed in the table, they are not included in the final count.

Thus, the total number of stars with reliable parameter measurements presented in this article is 195,478.
