Research Abstract |
In order to clarify the physics mechanism of anomalous resistivity in magnetic reconnection, we performed three-dimensional electromagnetic particle simulation in the open system. In the development of the simulation code, we succeeded in achieving an open boundary model which had a high accuracy and decreased unphysical noise. We could show analytically by simple model that the meandering motion of particles around the center of current layer excited the off-diagonal components of pressure tensor, and that it broke the frozen-in condition. In analysis of particle trajectories by using the virtual-reality system, it was clarified that non-thermal motion of ions strongly related to the heating process of the magnetic reconnection.
