Abstract

The stability of a thin magnetic tube located at different depths of the convective zone has been studied numerically and analytically. Three spectral regions are shown to be responsible for different processes related to solar activity. Numerical simulation shows that Parker instability in the high frequency domain (wave number m > 20) may accelerate magnetic fibrils to emerge into the solar atmosphere at supersonic speed. Such a physical process may be responsible for impulsive CME generation.
