Abstract
Theoretical time-dependent and two-component chromospheric models for late- type dwarfs are constructed based on acoustic and magnetic wave heating mec hanisms. The models are used to predict the theoretical range of chromosphe ric activity for these stars. Comparison of this range with the one establi shed observationally shows that the wave heating alone can explain most but not all of the observed range of stellar activity.
