DYNAMIC REGIMES OF PROMINENCE EVOLUTION

The dynamical model of a solar prominence taking into account plasma motion in the form of a cumulative flux was developed. Of great importance is the fact that the prominence plasma is partially ionized. Ion-neutral collisions in nonsteady flux conditions radically change the energetics and dynamics of the prominence model. In this case the equilibrium state described by the Kippenhahn-Schluter solutions becomes unstable, and various dynamic regimes of plasma compression, as well as monotonic or quasi-periodic expansion of the plasma can exist in the prominence.
