The Pre-Eruptive Structure and Initiation Mechanism(s) of CMEs
Abstract
Coronal mass ejections (CMEs) are huge expulsions of magnetized plasma from the low solar corona into interplanetary space, and the main driver of space weather disturbances in the terrestrial magnetosphere. Despite extensive research being conducted since the discovery of CMEs about 50 years ago, many important aspects of these enigmatic events are still not well understood. In this presentation, I will address two of these aspects, namely the nature of the pre-eruptive magnetic configuration and the physical mechanism(s) by which CME are triggered and driven. Specifically, I will discuss how numerical (MHD) simulations can help us to improve our understanding of CMEs.
