Abstract:
    We present the first APOKASC catalog of spectroscopic and
    asteroseismic data for dwarfs and subgiants. Asteroseismic data for
    our sample of 415 objects have been obtained by the Kepler mission in
    short (58.5s) cadence, and light curves span from 30 up to more than
    1000 days. The spectroscopic parameters are based on spectra taken as
    part of the Apache Point Observatory Galactic Evolution Experiment
    (APOGEE) and correspond to Data Release 13 of the Sloan Digital Sky
    Survey. We analyze our data using two independent Teff scales, the
    spectroscopic values from DR13 and those derived from SDSS griz
    photometry. We use the differences in our results arising from these
    choices as a test of systematic temperature uncertainties and find
    that they can lead to significant differences in the derived stellar
    properties. Determinations of surface gravity (logg), mean density
    (<ρ>), radius (R), mass (M), and age (τ) for the whole sample
    have been carried out by means of (stellar) grid-based modeling. We
    have thoroughly assessed random and systematic error sources in the
    spectroscopic and asteroseismic data, as well as in the grid-based
    modeling determination of the stellar quantities provided in the
    catalog. We provide stellar properties determined for each of the two
    Teff scales. The median combined (random and systematic)
    uncertainties are 2% (0.01dex; logg), 3.4% (<ρ>), 2.6% (R), 5.1%
    (M), and 19% (τ) for the photometric Teff scale and 2% (logg),
    3.5% (<ρ>), 2.7% (R), 6.3% (M), and 23% (τ) for the
    spectroscopic scale.
Description:
    The catalog consists of stars with detected solar-like oscillations in
    Kepler short-cadence data as reported in Chaplin+ (2011Sci...332..213C 2011Sci...332..213C)
    and with spectroscopic observations from the APOGEE-1 survey
    (Majewski+ 2017AJ....154...94M 2017AJ....154...94M). APOGEE spectra cover the H band,
    between 1.51 and 1.7um, at a resolution R=22500.
    This work extends the first APOKASC red giants catalog presented in
    Pinsonneault+ (2014, J/ApJS/215/19) to include 415 dwarf and subgiant
    stars. It is based on global seismic parameters Δν and
    νmax obtained from Kepler short-cadence asteroseismic data with
    length of light curves spanning from 30 up to 1055 days.
