Kepler flare star parameters from DR25

Coverage and stability of magnetic features are inspired by rotational modulation of light-curve variations and flare activity of stars are obtained using our automated flare detection algorithm. The results show that: (i) the flare time occupation ratio (or flare frequency) and the total power of flares increase by increasing relative magnetic feature coverage and contrast in F-M-type stars; (ii) magnetic feature stability is highly correlated with the coverage and the contrast of the magnetic structures, as this is the case for the Sun; and (iii) stability, coverage, and contrast of the magnetic features, time occupation ratio, and total power of flares increases for G-, K-, and M-type stars by decreasing the Rossby number due to the excess of the produced magnetic field from dynamo procedure until reaching to the saturation level.
