- Аннотация: We discuss the current observations of the most powerful non-steady phenomena on solar-like stars. While remaining within even the most extreme solar ideas, there is problematic to get the flare energy more than (3-5)×10^34erg, which is apparently an absolute upper limit for solar-type flares. For explanation of the higher flare energy, about of 10^36 erg, one need to adopt that spots with the magnetic field strength of a few kG should cover more than 30% of a hemisphere. This estimate leads to a mean magnetic field around 1kG. New observational evidences for a presence of the strong relict magnetic fields on solar-like stars appeared recently. We discuss to what extent it is necessary to change the mechanisms of convection and dynamo with a corresponding change in the models of the atmosphere. We consider possible ways of solving the problem of the energy of superflares.
