CORONAL MASS EJECTION INDUCED SOLAR INTERPLANETARY ENVIRONMENT

S. T. Wu

Abstract

We employ a helmet streamer and flux-rope magnetohydrodynamic model (Wu and Guo, 1997; Wu et al. 1999) to investigate the disturbed solar-interplanetary environment due to the propagation of the coronal mass ejection (CME). This CME is initiated due to an additional axial current of the flux-rope which destabilizes the streamer and launches a CME. We will track all physical parameters and fields when the CME passes through the solar-interplanetary environment (i.e. from 1 Rs to 1 A.U.) Specific attention will be paid to the formation, growth, and decay of the magnetohydrodynamic shock throughout the domain of the solar interplanetary environment. In addition, the disturbed configuration of the interplanetary magnetic field (MF) and corresponding plasma density contours will be presented.
