The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS
Travis S. Metcalfe, Jennifer L. van Saders, Sarbani Basu +29
Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones from stellar evolutio…
TESS Data for Asteroseismology: Timing verification
Carolina von Essen, Mikkel N. Lund, Rasmus Handberg +11
The Transiting Exoplanet Survey Satellite (TESS) is NASA's latest space telescope dedicated to the discovery of transiting exoplanets around nearby stars. Besides the main goal of…
TESS first look at evolved compact pulsators: Known ZZ Ceti stars of the southern ecliptic hemisphere as seen by TESS
Zs. Bognár, S. D. Kawaler, K. J. Bell +13
Context. We present our findings on 18 formerly known ZZ Ceti stars observed by the TESS space telescope in 120s cadence mode during the survey observation of the southern ecliptic…
Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi
William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81
Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…
TOI-257b (HD 19916b): A Warm sub-Saturn Orbiting an Evolved F-type Star
Brett C. Addison, Duncan J. Wright, Belinda A. Nicholson +91
We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS…
