Summary

Prominences are relatively cool (104 K) and dense (1011 cm−3) plasma clouds which may persist for 100 days or more in the midst of the much hotter (106 K) and more tenuous (109 cm−3) corona. Many observations imply that the magnetic field in and around prominences is responsible both for isolating prominences from the corona and for supporting them against gravity. It is not at all obvious how the magnetic field can do both these tasks, but the limited theoretical models that are available suggest that a magnetic-flux rope is involved. Here we argue using a new analytical model that the flux rope could also play a key role in the eruption of a prominence by supplying the magnetic energy necessary to drive the prominence outwards.
