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…
Anchoring Stellar Age Indicators: A Cross-Calibration of [C/N] and Gyrochronology Ages via the Age-Velocity-Dispersion Relation
Yuxi Lu, Marc H. Pinsonneault, Yuan-Sen Ting +4
Determining stellar ages is challenging, as it depends on other stellar parameters in a non-linear way and often relies on stellar evolution models to infer the underlying relation…
Chemically Self-Consistent Modeling of the Globular Cluster NGC 2808 and its Effects on the Inferred Helium Abundance of Multiple Stellar Populations
Emily M. Boudreaux, Brian C. Chaboyer, Amanda Ash +2
The helium abundances in the multiple populations that are now known to comprise all closely studied Milky Way globular clusters are often inferred by fitting isochrones generated…
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…
