Torus instability
arXiv:physics/0605217 · doi:10.1103/PhysRevLett.96.255002
Abstract
The expansion instability of a toroidal current ring in low-beta magnetized plasma is investigated. Qualitative agreement is obtained with experiments on spheromak expansion and with essential properties of solar coronal mass ejections, unifying the two apparently disparate classes of fast and slow coronal mass ejections.
