Abstract:
For ongoing studies of the role of rotation in stellar evolution, we
require large catalogs of rotation periods for testing and refining
gyrochronology. While there is a wealth of data from the Kepler and K2
missions, the Transiting Exoplanet Survey Satellite (TESS) presents
both an opportunity and a challenge: despite its all-sky coverage,
rotation periods remain hard to detect. We analyzed individual TESS
sectors to detect short-period stellar rotation, using only parameters
measured from light curves for a robust and unbiased method of
evaluating detections. We used random forest classifiers for vetting,
trained on a large corpus of period measurements in Kilodegree
Extremely Little Telescope data from the Oelkers et al. catalog and
using TESS full-frame image light curves generated by eleanor.
Finally, using data from the first 26 sectors of TESS, we analyzed
432704 2minutes cadence single- sector light curves for FGKM dwarfs.
We detected 16800 periods in individual sector light curves, covering
10,909 distinct targets, and we present a catalog of the median period
for each target as measured by a Lomb-Scargle periodogram.
Description:
In this work, we present a pipeline to detect and vet stellar rotation
in individual TESS sectors, and an output catalog of period detections
across 10909 targets.
