Hybrid Simulation of Space Plasmas: Models with Massless Fluid Representation of Electrons. VI. Magnetotail Current Sheets

Abstract

This is a survey of literature on hybrid simulation of magnetotail current sheets. The “traditional” electromagnetic hybrid model (with ions as particles and electrons as a massless fluid) is briefly described together with its main numerical schemes. This is followed by a description of the “modified” hybrid model in which the generalized Ohm's law includes both electron inertia and evolution of the total electron pressure tensor. The survey part examines the literature on hybrid simulation of current sheets in a quiet magnetotail; formation of current sheets; dynamics of ions in current sheets; formation and evolution of plasmoids.
