Abstract

In this chapter we shall consider dynamics of quiescent prominences. These amazing phenomena offer excellent opportunity to study fundamental properties of various plasma instabilities, and also address to some of the most enigmatic features of solar atmosphere. We shall combine the observational evidence and theory to identify such instabilities as:

  1. (1)

    prominence cavity formation and its evolution, associated with a large scale screw pinch instability;

  2. (2)

    development of regular series of plumes and spikes typical to the Rayleigh–Taylor (RT) instability; and

  3. (3)

    the appearance of growing ripples at the prominence/corona interface, often followed by a sudden collimated mass up- and downflows, attributed to the Kelvin–Helmholtz (KH) instability.

We shall specify the conditions for transition from a linear (rippling mode) to nonlinear stage of the KH instability, known to have an explosive character. We show examples of a practical use of direct measurements of the instability parameters and also briefly discuss the natural occurrence of greenhouse-like effect under prominence body.
