Abstract:
We present a catalog of ∼100000 periodic variable stars in Transiting
Exoplanet Survey Satellite (TESS) full-frame image data among members
of widely distributed moving groups identified with Gaia in the
previous papers in the series. By combining the periods from our
catalog attributable to rotation with previously derived rotation
periods for benchmark open clusters, we develop an empirical
gyrochronology relation of angular momentum evolution that is valid
for stars with ages 10-1000Myr. Excluding stars rotating faster than
2days, which we find are predominantly binaries, we achieve a typical
age precision of ∼0.2-0.3dex and improving at older ages. Importantly,
these empirical relations apply to not only FGK-type stars but also
M-type stars, due to the angular momentum distribution being much
smoother, simpler, continuous, and monotonic as compared to the
rotation period distribution. As a result, we are also able to begin
tracing in fine detail the nature of angular momentum loss in low-mass
stars as functions of mass and age. We characterize the stellar
variability amplitudes of the cool stars as functions of mass and age,
which may correlate with the starspot covering fractions. We also
identify pulsating variables among the hotter stars in the catalog,
including δScuti, γDor, and slowly pulsating B-type
variables. These data represent an important step forward in being
able to estimate precise ages of FGK- and M-type stars in the field,
starting as early as the pre-main-sequence phase of evolution.
Description:
We generate light curves from Transiting Exoplanet Survey Satellite
Full Frame Images (TESS/FFI) data for stars within 500pc and with
known ages from the Gaia-based Theia catalog
(PaperII; Kounkel+, 2020, J/AJ/160/279). Our resulting catalog of
∼100000 periodic variable stars contains primary, and in some cases
secondary, periods up to a maximum of 12days.
