The YREC Stellar Evolution Code: Public Data Release

Marc H. Pinsonneault, Jennifer L. van Saders, Lyra Cao +11

In this paper we present the public release of the Yale Rotating Evolution Code (YREC). YREC is a stellar evolution code that covers brown dwarfs and stars across a wide range of m…

Beyond the Nyquist frequency: Asteroseismic catalog of undersampled Kepler late subgiants and early red giants

B. Liagre, R. A. García, S. Mathur +9

Subgiants and early red giants are crucial for studying the first dredge-up, a key evolutionary phase where the convective envelope deepens, mixing previously interior-processed ma…

Modeling Asteroseismic Yields for the Roman Galactic Bulge Time-Domain Survey

Trevor J. Weiss, Noah J. Downing, Marc H. Pinsonneault +10

The Galactic Bulge Time Domain Survey (GBTDS) of the Roman Space Telescope will take high cadence data of the Galactic bulge. We investigate the asteroseismic potential of this sur…

Improving the stellar age determination through joint modeling of binarity and asteroseismology -- Grid modeling of the seismic red-giant binary KIC 9163796

D. H. Grossmann, P. G. Beck, S. Mathur +12

Context. Typical uncertainties of ages determined for single star giants from isochrone fitting using single-epoch spectroscopy and photometry without any additional constraints ar…

Testing the Breakdown of the Asteroseismic Scaling Relations in Luminous Red Giants

Amanda L. Ash, Marc H. Pinsonneault, Mathieu Vrard +1

Nearly all cool, evolved stars are solar-like oscillators, and fundamental stellar properties can be inferred from these oscillations with asteroseismology. Scaling relations are c…

APOKASC-3: The Third Joint Spectroscopic and Asteroseismic catalog for Evolved Stars in the Kepler Fields

Marc H. Pinsonneault, Joel C. Zinn, Jamie Tayar +38

In the third APOKASC catalog, we present data for the complete sample of 15,808 evolved stars with APOGEE spectroscopic parameters and Kepler asteroseismology. We used ten independ…
