TESS Stellar Rotation up to 80 days in the Southern Continuous Viewing Zone
Zachary R. Claytor, Jennifer L. van Saders, Lyra Cao +3
The TESS mission delivers time-series photometry for millions of stars across the sky, offering a probe into stellar astrophysics, including rotation, on a population scale. Howeve…
Constraints on star formation in Orion A from Gaia
Jairo A. Alzate, Gustavo Bruzual, Marina Kounkel +4
We develop statistical methods within a Bayesian framework to infer the star formation history from photometric surveys of pre-main sequence populations. Our procedures include cor…
Seven Classes of Rotational Variables From a Study of 50,000 Spotted Stars with ASAS-SN, Gaia, and APOGEE
Anya Phillips, C. S. Kochanek, Tharindu Jayasinghe +4
We examine the properties of rotational variables from the ASAS-SN survey using distances, stellar properties, and probes of binarity from DR3 and the…
Stellar Characterization and Radius Inflation of Hyades M Dwarf Stars From the APOGEE Survey
Fábio Wanderley, Katia Cunha, Diogo Souto +23
We present a spectroscopic analysis of a sample of 48 M dwarf stars () from the Hyades open cluster using high-resolution H-band spectra from the…
Spectroscopic identification of rapidly rotating red giant stars in APOKASC-3 and APOGEE DR16
Rachel A. Patton, Marc H. Pinsonneault, Lyra Cao +6
Rapidly rotating red giant stars are astrophysically interesting but rare. In this paper we present a catalog of 3217 active red giant candidates in the APOGEE DR16 survey. We use…
ABYSS I: Targeting strategy for APOGEE & BOSS young star survey in SDSS-V
Marina Kounkel, Eleonora Zari, Kevin Covey +15
The fifth iteration of the Sloan Digital Sky Survey (SDSS-V) is set to obtain optical and near-infrared spectra of 5 million stars of all ages and masses throughout the Milky…
Core-envelope decoupling drives radial shear dynamos in cool stars
Lyra Cao, Marc H. Pinsonneault, Jennifer L. van Saders
Differential rotation is thought to be responsible for the dynamo process in stars like our Sun, driving magnetic activity and star spots. We report that star spot measurements in…
