Numerical Modeling of Coronal Mass Ejections Based on Various Pre-Event Model Atmospheres

Wu, S. T.; Poletto, G.; Suess, S. T. +1 more

We examine how the initial state (pre-event corona) affects the numerical MHD simulation for a coronal mass ejection (CME). Earlier simulations based on a pre-event corona with a homogeneous density and temperature distribution at the lower boundary (i.e., solar surface) have been used to analyze the role of streamer properties in determining the …
