相对论电流片中磁重联的稳定性

Stabilization of Magnetic Reconnection in Relativistic Current Sheet

Masahiro Hoshino

摘要:

最近,相对论热等离子体被强磁场限制的磁重联在与天体物理对象(例如,脉冲星磁层和磁星)。然而,在等离子体片与相对论性高速漂移电流重联尚未调查。因此,我们从理论和计算的角度研究了相对论热等离子体片中高速漂移流的相对论重联增长率。因此,我们认为,相反的相对论重联的快速能量耗散的传统理解,磁重联的增长被抑制。

英文摘要:

Recently, magnetic reconnection, where a relativistically hot plasma is confined by a strong magnetic field, has received great attention in relation to astrophysical objects (e.g., pulsar magnetosphere and magnetar). However, reconnection with relativistic high-speed drift current in the plasma sheet has not been investigated yet. Thus, from both the theoretical and computational points of view, we studied the growth rate of relativistic reconnection for the high-speed drift current in a relativistically hot plasma sheet. Consequently, we argue that, contrary to the conventional understanding of the fast energy dissipation by the relativistic reconnection, the growth of magnetic reconnection is suppressed.
