They Won't Be Giants: Missing Metal-Rich RGB Stars in Gaia Data Indicate Truncated Stellar Evolution
Yuxi Lu, Madeline Howell, Marc H. Pinsonneault +3
We investigate the population of luminous red giant branch stars as a function of metallicity using Gaia XP metallicity combined with SDSS-V, GALAH, and LAMOST. After applying unif…
Detecting Solar-Like Oscillations in the Highest Mass TESS Giants
Noah J. Downing, Madeline Howell, Marc H. Pinsonneault +4
The authors analyze all‑sky TESS data to detect solar‑like oscillations in high‑mass red‑giant stars, identifying 98 oscillating giants (including 43 above 3 M⊙) and revealing a sy…
The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
The paper describes the twentieth data release (DR20) of the Sloan Digital Sky Survey, providing over 3 million new optical spectra from the SDSS‑V Milky Way, Black Hole, and Local…
Ensemble Kinematic Ages for 1.5 Million LAMOST Stars
Yuxi Lu, Marc H. Pinsonneault
We present a framework for inferring stellar ages from spectroscopic stellar parameters, calibrated with ensemble kinematics by averaging over the median vertical action, , fo…
TESS Asteroseismology of Red Giants in the Old Metal-Rich Open Clusters NGC 188 & NGC 6791
Madeline Howell, Jennifer A. Johnson, Marc H. Pinsonneault +5
Open clusters are fundamental laboratories for investigating stellar and Galactic evolution, and serve as important benchmarks for asteroseismic analyses. Using a boutique method t…
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…
