Stability and eruption of prominences
Abstract
The application of stability theory to quiescent solar prominences is examined, reviewing the results of recent investigations. The governing equations for the primary MHD instabilities (kink-mode, sausage-mode, and Rayleigh-Taylor) are presented; normal-mode, energy-method, and nonequilibrium approaches to their solution are outlined; and particular attention is given to the effect of the dense photosphere, ballooning modes, coronal arcades, distributed current models and eruptive instability, localized modes and small-scale structure, and arcades containing a current sheet. Also discussed are the problem of thermal stability, resistive instabilities and tearing modes, the effect of line tying, and a simple model describing prominence eruption and coronal mass ejection.
