Abstract:

A summary of progress on the theory and simulation of plasmoid formation and propagation is presented. Progress occurred in two areas. First, an analytical model or core-halo dynamics was derived for an arrow-type plasmoid. This model predicts halo expansion that is approximately linear in time with a velocity proportional to the core ion sound speed and a core expansion that is logarithmic in time. Second, simulation efforts have successfully formed and propagated plasmoids with core and halo structure.
