Fast Magnetic Reconnection Associated With Kink Modes
نویسندگان
چکیده
A three-dimensional particle-in-cell simulation in a large system demonstrates that a kink mode significantly contributes to a fast reconnection by providing magnetic dissipation through anomalous resistivity. The anomalous resistivity is generated due to the electron heating in the thin electron current sheet. It is interesting that, although the kink mode broadens the width of the current sheet and decreases the inertia resistivity, the anomalous resistivity compensates the depletion so as to keep a high reconnection rate. The present result suggests that the electron dynamics in the electron diffusion region is automatically adjusted so as to produce sufficient dissipation for the fast magnetic reconnection.

Coronal magnetohydrodynamic waves and oscillations: observations and quests.
Coronal seismology, a new field of solar physics that emerged over the last 5 years, provides unique information on basic physical properties of the solar corona. The inhomogeneous coronal plasma supports a variety of magnetohydrodynamics (MHD) wave modes, which manifest themselves as standing waves (MHD oscillations) and propagating waves. Here, we briefly review the physical properties of obs...

We study the current-driven kink instability with a three-dimensional MHD spectral code, under conditions appropriate for the convection zone of the Sun. Our goal is to determine whether the kink instability can explain the unusual morphology of certain ““ d-spot ÏÏ active regions. The characteristics of these d-spots are unusually large tilt upon emergence, subsequent rotation, compactness dur...

We study the role of the guide field in relativistic magnetic reconnection in a Harris current sheet of pair (e±) plasmas, using linear theories and particlein-cell (PIC) simulations. Two-dimensional PIC simulations exhibit the guide field dependence to the linear instabilities; the tearing or reconnection modes are relatively insensitive, while the relativistic drift-kink instability (RDKI), t...
