Resistive and Eruptive Instability by Ponderomotive Force with High-Frequency Plasma Oscillations

摘要

The authors investigated the subtle interaction between the magnetohydrodynamic (MHD) and high frequency plasma waves and they derived the coupling equations for the phenomena. On the basis of the formalism, they examined the modulation instabilities by an electromagnetic solition in a current sheet and showed that there is a resistive instability for constant-psi approximation (i.e., uniform magnetic field configuration), which eventually turns into an eruptive instability at the onset of the magnetic field reconnection.
