Catalog of Stellar Flares in 219 M-dwarfs
Listed in IVOA Registry (Virtual Observatory)
We present a study of the relationship between Galactic kinematics, flare rates, chromospheric activity, and rotation periods for a volume-complete, nearly all-sky sample of 219 single stars within 15 pc and with masses between 0.1 and 0.3 M{sun} observed during the primary mission of TESS.
Description
We find all stars consistent with a common value of {alpha}=1.984{+/-}0.019 for the exponent of the flare frequency distribution. Using our measured stellar radial velocities and Gaia astrometry, we determine Galactic UVW space motions.
We find 78% of stars are members of the Galactic thin disk, 7% belong to the thick disk, and for the remaining 15% we cannot confidently assign membership to either component. If we assume star formation has been constant in the thin disk for the past 8Gyr, then based on the fraction that we observe to be active, we estimate the average age at which these stars transition from the saturated to the unsaturated flaring regime to be 2.4{+/-}0.3Gyr.

This is consistent with the ages that we assign from Galactic kinematics: we find that stars with rotation period Prot <10days have an age of 2.0{+/-}1.2Gyr, stars with 10days<Prot<~90days have an age of 5.6{+/-}2.7Gyr, and stars with Prot>90days have an age of 12.9{+/-}3.5Gyr. We find that the average age of stars with Prot<10 days increases with decreasing stellar mass from 0.6{+/-}0.3Gyr (0.2-0.3M{sun}) to 2.3{+/-}1.3Gyr (0.1-0.2 M{sun}).
