Quasi-Static Evolution, Catastrophe, and "Failed" Eruption of Solar Flux Ropes

Abstract

This document presents the first theoretical treatment of the dynamical evolution of solar flux ropes subject to slowly increasing magnetic energy, encompassing quasi-static evolution, catastrophic transition to an eruptive state, rapid cessation of the eruption, and ensuing quasi-equilibrium evolution. The flux ropes, initialized to be force-free, self-consistently evolve into non-force-free equilibria while maintaining kink stability. In the post-eruption equilibria, tension force of the toroidal self field and the pressure gradient force combine to balance the major radial hoop force. The macroscopic forces on the flux ropes and onset conditions are quantified
