Abstract

I point out that the flare energetics has a central role in our understanding of the nature of the flare phenomena /see also Grandpierre, 1986/. Combining the recent observational data with the values expected by the magnetic flare theories/MFT/ I show here that they are inconsistent with a lot of basic observational fact. I calculate the energies and the respective time scales of flares by the convective flare theory/CFT/ and I find that the results seem to be consistent with the observations. I present some prophecies of the CFT for the future observations as the relation between the energy liberation in central stellar regions and the flare activity, dependence of flare activity on stellar ages and spot dynamics.
