TL;DR
The APOKASC catalog combines asteroseismic and spectroscopic data for stars observed by Kepler and APOGEE, providing valuable stellar parameters and insights into spectral sensitivities.
Contribution
This paper introduces the APOKASC catalog, integrating seismic and spectroscopic data for stars, and discusses the derivation and uncertainties of stellar parameters from APOGEE spectra.
Findings
Spectroscopic parameters derived from APOGEE spectra show sensitivity to Teff.
Uncertainties in stellar parameters are characterized.
Spectral sensitivity varies among different stellar parameters.
Abstract
I report on the APOKASC catalog, a joint effort between the Kepler Asteroseismic Science Consortium and the SDSS-III APOGEE spectroscopic survey. It will contain both seismic and spectroscopic values for stars observed by both surveys. I discuss the derivation of spectroscopic parameters and their uncertainties from the H-band spectra delivered by the APOGEE spectrograph, illustrating the sensitivity of stellar spectra to some parameters, such as Teff, and lack of sensitivity to others, such as logg.
