| Zusammenfassung |
| We investigate the coupling between current
and tearing instability modes of a thin current sheet using the particle code
GISMO. We identify pure tearing modes (kx≠ 0), instabilities in the
current flow direction (ky≠ 0) and general 3D reconnection modes (kx≠ 0 and ky≠ 0). Our results give evidence that the coupling between
tearing modes and current instabilities plays an important role for spontaneous
magnetic reconnection. These modes give a substantial contribution to magnetic
reconnection, additional to the well known 2D tearing mode. When allowing
reconnection to occur in three spatial dimensions, a configuration, which was
initially invariant in the current How direction, develops into a configuration
with no invariant direction. |
