AbstractImages of post-flare loop systems recorded in coronal green- and red-line emissions display occasional transient enhancements at the intersection of some loops where they come into contact. Such enhancements are investigated in terms of the likely plasma processes involved in these dynamic events. For this, the interaction between magnetohydrodynamic and high frequency plasma waves, and the instability associated with an electromagnetic solitary wave in a current sheet, are studied. It is shown that there is a resistive instability, which eventually turns into an eruptive instability at the onset of magnetic field reconnection. The numerical results are consistent with the observations. Thus the phenomenon of occasional enhancements in the vicinity of the projected intersection of two loops may be basically interpreted by this theory of magnetic field reconnection driven by ponderomotive force.
