Our best-fit flare evolution model showing the predicted FFD evaluated at four age bins for a 0.5 M_⊙ (top) and 1.0 M_⊙ star (bottom). Although the change in FFD slopes as a function of age is negligible, the difference as a function of mass is significant. Note: these FFDs are drawn at the same energy ranges for ease of comparison, but do not correspond to the specific flare energies detected at these masses.
