TESS monitoring campaign of low-mass flare stars

We find QPPs in both the rise and decay phases of flares, including a rise-phase QPP in a large flare from Proxima Cen. We confirm that the Davenport+ (2014ApJ...797..122D) template provides a good fit to most classical flares observed at high cadence, although 9% favor Gaussian peaks instead. We characterize the properties of complex flares, finding 17% of complex flares exhibit "peak-bump" morphologies composed of a large, highly impulsive peak followed by a second, more gradual Gaussian peak.

We also estimate the UVC surface fluences of temperate planets at flare peak and find one-third of 10^34^erg flares reach the D90 dose of Deinococcus radiodurans in just 20s in the absence of an atmosphere.
