Title:  M dwarf search for pulsations and flare studies within Kepler Guest Observer program

We have done time-series analysis to search for pulsations in a sample of five M dwarfs observed in short-cadence within Kepler Guest Observer program. High cadence sampling is essential to detect the shortest pulsations predicted theoretically in the 20 minute range and to enable high time-resolution analysis of flares. Three of the targets present stellar activity and two rotational modulation. We find that white light flares are present in the M dwarfs with rotational periods less than 20 days, and that their energy-frequency relations are comparable to traditional flare stars. The rapidily rotating M4 star GJ 1243 shows the strongest and most frequent flares. Pulsations have not been found to a detection limit of several parts per million.
