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.
