Scientific paper

We present recent developments in the mathematical modeling and numerical simulations of the initiation and interplanetary evolution of CMEs in the framework of ideal magneto-hydrodynamics (MHD). In earlier work, we reconstructed simple, axisymmetric (2.5D) solar wind models for the quiet Sun. Next, we mimicked fast CME events by superposing high-density plasma blobs on the background wind and launching them in a given direction at a certain speed, enabling the study of the evolution of the fast CME shocks, their effects on the coronal field and background solar wind. Here, more realistic CME onset models are presented to investigate the possible role of magnetic foot point shearing and magnetic flux emergence/disppearence as triggering mechanisms of the instability. In particular, the well-known breakout model has been superposed on a solar wind model and it is shown that both foot point shearing and magnetic flux emergence can be used as a triggering mechanism in this model.
