Main Sequence Star Super-flare Frequency based on Entire Kepler Data

Abstract We wrote and used an automated flare detection Python script to search for super-flares on main sequence stars of types A, F, G, K M in Kepler’s long-cadence data from Q0 Q17. studied the statistical properties occurrence rate super-flares. For G-type set, we compared our results with previous Okamoto et al. by splitting set into four rotational bands. found similar power-law indices frequency distribution. Hence, show that inclusion a high-pass filter, sample biases, gyrochronology completeness is no significance, as are those estimated super-flare dwarfs energy 10 35 erg occurs star once every 4360 yr. 4637 1896 dwarfs. Moreover, identified 321, 1125, 4538 5445 136, 522, 770 312 M, respectively. ascertained ( dN / dE ) versus energy, E , shows distribution dN / mathvariant="italic">dE ∝ E − α where α ≃ 2.0 2.1 spectral F-type M-type stars. In contrast, obtained 1.3 A-type suggests conditions differ other spectral-type note increase incidence decrease
