We searched for flares using a volume-complete sample of stars with masses between 0.1-0.3 solar masses and that reside with in 15 parsecs.
Relationship between Flare Rate and StellarRotation
We find that the rate of flares as a function of rotation period/Rossby number shows saturated behavior above a critical value and then sharply declines below this value.
Flare Rate and Emission of H-alpha
We find that measuring the equivalent width of H-alpha can yield an estimate for the flare rate of any given mid-to-late M dwarf. Determining the flare rate for these highly magnetically active stars is essential to understanding the radiation environments the planets orbiting them are subject to.
