Testing Asteroseismology with APOGEE Star Clusters
Marc Pinsonneault (Ohio State University), et al.

The APOGEE survey has obtained high resolution H band spectra for Kepler red giants and for large numbers of star cluster members. We explore the cluster data, both within and outside of the Kepler fields, as a test of asteroseismic surface gravity and mass measurements. Clusters provide independent checks on surface gravity (from cluster age, distance, and extinction), the mass dependence of the first dredge-up (as measured by C and N), and asteroseismic / spectroscopic inferences about evolutionary state. We discuss the current state of agreement between the two and prospects for improvement using upcoming data, including K2.
