Simulating Coronal Mass Ejections in the Heliosphere

Abstract

Coronal mass ejections (CMEs) and their attendant eruptive flares (EFs) are the most explosive events in the solar system. Magnetic reconnection, arguably the most universal of heliophysical processes, is widely accepted as playing crucial roles in these phenomena. In this paper we summarize some recent advances in understanding CMEs and EFs developed from first-principles numerical simulations of slowly evolving configurations that transition suddenly to violent eruptions. The study emphasizes the role of magnetic complexity in the solar sources of the most energetic events, which can be exploited by magnetic reconnection to unleash the mass, magnetic flux, and energies of the CME and the EF on the Heliosphere
