Magnetic Topologies and Two-class Coronal Mass Ejections : a Numerical Magnetohydrodynamic Study

Abstract

White-light observations of the solar corona show that there are two characteristic types of Coronal Mass Ejections (CMEs) in terms of speed-height profiles: so-called fast CMEs that attain high speeds low in the corona and slow CMEs that gradually accelerate from low initial speeds. Low and Zhang have recently proposed that fast and slow CMEs result from… (More)
