Title: A radiating one-dimensional current sheet configuration

Abstract

The structure of the x-independent (one-dimensional) forced current sheet including a self-consistent B{sub y} component is investigated for the case of small normal field component, B{sub z}/B{sub o} {much_lt} 1. A hybrid (kinetic ions, massless fluid electrons) simulation model is used to demonstrate that such a current sheet has a time-dependent structure which radiates incompressible Alfven waves with amplitude of the order of the asymptotic (lobe) field strength B{sub o}. The central density enhancement acts as the source of a propagating wavetrain in which B{sub x} rotates into B{sub y} and back again. One of the characteristic signatures of the radiating current sheet is the presence of a reversal in B{sub x} (or B{sub y}) without a corresponding increase in density. 25 refs., 8 figs.
