Quiescent and Eruptive Prominences
Most spectacular of the solar features are the streams of hot gas, called prominences, ...
the centre to the surface, these gases are gases only in the sense that if the pressure of neighbouring and outward parts gravitating towards the centre were relaxed, they would expand explosively, as we see happening in the eruptive prominences.
Mass of hot, hydrogen rising from the Sun's chromosphere, best observed indirectly during a total eclipse. Eruptive prominences are violent in force and may reach heights of 2 million km; ...
Streaming arches and their stability for days at a time are associated with magnetic forces acting on the charged particles in the loops. The violently eruptive prominences that are sometimes observed are associated with corresponding sudden changes ...
