Numerical simulations of solar flare processes
Abstract
Using particle-in-cell models the processes of the current sheet fragmentation, return current formation and electron beam interaction with the current sheet are studied in details. Computations in the 3-D model with two current sheets in the Buneman instability regime and with the extended dimension in the electric current direction show that the current sheets become very fragmented. The anomalous resistivity is estimated. Furthermore, a formation of the return current due to electromagnetic effects is presented. Finally, it is shown that the electron beam can trigger the flare magnetic reconnection.
