MHD (Magnetohydrodynamic) Slow Shocks in Coronal and Interplanetary Space.

摘要

The overall objective of this project is to study shock waves of the solar terrestrial medium in coronal and interplanetary space. This research will enhance our understanding on the propagation of large amplitude disturbances from the solar corona through the interplanetary space. Work accomplished during the past three years includes: 1) a demonstrating example showing the formation of slow shock pairs associated with CMEs in a coronal environment; 2) a parametric study of slow shocks in the entire domain of a three-dimensional parameter space, the A, theta, Beta-space; 3) the large scale geometry of traveling interplanetary shocks; 4) the transition of slow shocks to fast shocks in the inner solar wind; and 5) the evolution of CME associated shocks and their interplanetary manifestations.
