Toward the true number of flaring giant stars in the Kepler field: Are their flaring specialities associated with their being giant stars?

Aims. We aim to give a reliable estimate of the number of flaring giant stars in the Kepler field. By analyzing the flaring activity of these stars, we explored their flare statistics and the released flare energies. The role of oscillation in suppressing magnetic activity was also investigated. We searched for flaring specialities that may be associated with the giant nature across a sample of flaring giant stars.Methods. We searched for flares using the approximate to 4 yr long Kepler data on a sample of 706 stars compiled from two lists of flaring giants (log g
