The APOKASC Catalog: An Asteroseismic and Spectroscopic Joint Survey of Targets in the Kepler Fields
Marc H. Pinsonneault, Yvonne Elsworth, Courtney Epstein +42
We present the first APOKASC catalog of spectroscopic and asteroseismic properties of 1916 red giants observed in the Kepler fields. The spectroscopic parameters provided from the…
Bayesian distances and extinctions for giants observed by Kepler and APOGEE
Thaíse S. Rodrigues, Léo Girardi, Andrea Miglio +30
We present a first determination of distances and extinctions for individual stars in the first release of the APOKASC catalogue, built from the joint efforts of the Apache Point O…
Early Results from APOKASC
Courtney Epstein
Asteroseismology and spectroscopy provide complementary constraints on the fundamental and chemical properties of stars. I describe the first results from APOKASC, a collaboration…
Testing the Asteroseismic Mass Scale Using Metal-Poor Stars Characterized with APOGEE and Kepler
Courtney R. Epstein, Yvonne P. Elsworth, Jennifer A. Johnson +29
Fundamental stellar properties, such as mass, radius, and age, can be inferred using asteroseismology. Cool stars with convective envelopes have turbulent motions that can stochast…
Calibrations of Atmospheric Parameters Obtained from the First Year of SDSS-III APOGEE Observations
Sz. Mészáros, J. Holtzman, A. E. García Pérez +25
The SDSS-III Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a three year survey that is collecting 100,000 high-resolution spectra in the near-IR across multipl…
How Good a Clock is Rotation? The Stellar Rotation-Mass-Age Relationship for Old Field Stars
Courtney R. Epstein, Marc H. Pinsonneault
The rotation-mass-age relationship offers a promising avenue for measuring the ages of field stars, assuming the attendant uncertainties to this technique can be well characterized…
