[PEM26-06] Resistive magnetic reconnection in a plasma stream
Keywords:magnetic reconnection, plasma stream, MHD
Although several theoretical and numerical studies for the tearing instability in an anti-parallel magnetic field including a field-aligned plasma stream, i.e., the streaming tearing instability, have been reported so far , the nonlinear dynamics of well-developed magnetic reconnection in the plasma stream has not been clarified yet. Thus, the objective of this paper is to explore the nonlinear dynamics of resistive magnetic reconnection in the plasma stream using the MHD simulation. In this study, nonlinear magnetic reconnection was triggered by a large perturbation in the Harris-type equilibrium with a localized field-aligned plasma stream. The results indicated that the current sheet structure of the reconnection point is varied depending on the bulk speed of the localized plasma stream. We found that the current sheet can be localized when the bulk speed is less than the Alfven speed.
