Abstract:
Asteroseismology has become widely accepted as a benchmark for
accurate and precise fundamental stellar properties. It can therefore
be used to validate and calibrate stellar parameters derived from
other approaches. Meanwhile, one can leverage large-volume surveys in
photometry, spectroscopy, and astrometry to infer stellar parameters
over a wide range of evolutionary stages, independently of
asteroseismology. Our pipeline, SEDEX (http://github.com/Jieyu126/SEDEX),
compares the spectral energy distribution predicted by the MARCS and
BOSZ model spectra with 32 photometric bandpasses, combining data from
nine major, large-volume photometric surveys. We restrict the analysis
to targets with available spectroscopy from the APOGEE, GALAH, and
RAVE surveys to lift the temperature-extinction degeneracy. The cross-
survey atmospheric parameter and uncertainty estimates are homogenized
with artificial neural networks. Validation of our results with CHARA
interferometry, Hubble Space Telescope CALSPEC spectrophotometry, and
asteroseismology shows that we achieve high precision and accuracy. We
present a catalog of improved interstellar extinction
(σAv∼0.14mag) and stellar radii (σR/R∼7.4%) for
∼1.5 million stars in the low-to-high-extinction (AV≲6mag) fields
observed by the spectroscopic surveys. We derive global extinctions
for 184 Gaia DR2 open clusters and confirm the differential extinction
in NGC 6791 and NGC 6819, which have been subject to extensive
asteroseismic analysis. Furthermore, we report 36854 double-lined
spectroscopic main-sequence binary candidates. This catalog will be
valuable for providing constraints on detailed modeling of stars and
for constructing 3D dust maps of the Kepler field, the TESS Continuous
Viewing Zones, and the PLATO long-duration observation fields.
Description:
Our targets were selected from three large-volume, high-resolution
spectroscopic campaigns, i.e., APOGEE (spectral resolution ∼22500;
DR17, Abdurro'uf & Aerts 2022ApJS..259...35A 2022ApJS..259...35A), GALAH (spectral
resolution ∼28000; DR3, Buder+ 2021, J/MNRAS/506/150), and RAVE
(spectral resolution ∼7500; DR6, Steinmetz+ 2020, III/283).
Observed SEDs were constructed from 32 bandpasses of nine photometric
databases, with the following photometric systems when available:
Gaia DR3 (Riello+ 2021, J/A+A/649/A3),
Pan-STARRS DR1 (Chambers+ 2016, II/349), APASS DR9 (Henden+ 2016, II/336),
Tycho2 (Hog+ 2000, I/259), Hipparcos (van Leeuwen 2007, I/311),
SkyMapper DR2 (Onken+ 2019PASA...36...33O 2019PASA...36...33O), Sloan Digital Sky Survey
(SDSS) DR13 (Alam+ 2015, V/147), 2MASS (Cutri+ 2003, II/246), and
ALLWISE (Cutri+ 2013, II/328). See Section 2.3.
