| Abstract: |
CMEs consist of an erupted filament (the core), flux loops that lie over the filament (the leading edge), and a cavity between the core and the leading edge. Some CMEs additionally have extra characteristics: a twisted structure along the loop with the structure like a convex lens (Illing & Hundhausen 2000) at the loop top. We consider the propagation of torsional Alfvén waves (TAWs) as the cause of these extra characteristics, and have studied this with a 3D MHD simulation. Our simulation shows that TAW propagation provides a likely explanation of all these characteristics, including the existence of two sub-types. Additionally TAWs can carry plasma from the chromosphere to the corona along the loop. Based on results of our simulations and observations we propose a new scenario concerning the occurrence of CMEs. |
