Scientific paper

The X-line retreat problem is investigated by a large scale two-dimensional full particle simulation. In the case where the obstacle sits close to the X-line, the collision between the reconnection flow and the obstacle may affect on the process right at the X-point. Carrying out a two-dimensional full particle simulation with an asymmetric condition for the reconnection flow, Oka et al. (presented in this meeting) found that the X-line moves away from the obstacle with the speed of ~ 0.1 Alfven speed. To examine more long-time evolution of the X- line retreat, we have performed a simulation of the X-line retreat with a larger simulation box whose scale size is more than ~ 100 ion inertia length. In this presentation, we will demonstrate how the X-line retreat evolves in the macroscopic view and will discuss its relation to the microscopic process in the X-line region.
