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…
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…
On the signatures of flare-induced global waves in the Sun: GOLF and VIRGO observations
Brajesh Kumar, Savita Mathur, Rafael A. Garcia +1
Recently, several efforts have been made to identify the seismic signatures of flares and magnetic activity in the Sun and Sun-like stars. In this work, we have analyzed the disk-i…
Analysis of the acoustic cut-off frequency and HIPs in six Kepler stars with stochastically excited pulsations
A. Jimenez, R. A. Garcia, F. Perez Hernandez +1
Gravito-acoustic modes in the Sun and other stars propagate in resonant cavities with a frequency below a given limit known as the cut-off frequency. At higher frequencies, waves a…
Rotation and magnetism of Kepler pulsating solar-like stars. Towards asteroseismically calibrated age-rotation relations
R. A. Garcia, T. Ceillier, D. Salabert +16
Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied for thousands of stars…
Magnetic activity of F stars observed by Kepler
S. Mathur, R. A. Garcia, J. Ballot +6
The study of stellar activity is important because it can provide new constraints for dynamo models, when combined with surface rotation rates and the depth of the convection zone.…
