引力作用下的强可压缩流片
Strongly compressible current sheets under gravitation
摘要：
在天体物理学中，许多风暴事件都是由于突然的磁能释放而发生的。这是可能的，如果一个磁配置突然改变其拓扑结构，一个事件通常被称为磁重联。众所周知，纯欧姆衰变是低效的，发生在宇宙学时期（由于巨大的特征尺度$L$）。认识到电流片的存在加速了该过程，但仍然不足以$^{1,2,3,4,5}$。我们表明，在高度可压缩和实质上的引力介质中，重联是足够快的风暴事件。因此，高度可压缩的情况为解释暴力事件提供了令人兴奋的机会，尽管全尺寸可压缩和重力模拟被证明是相当具有挑战性的。
英文摘要：
Many stormy events in astrophysics occur due to the sudden magnetic energy release. This is possible if a magnetic configuration abruptly changes its topology, an event usually referred to as magnetic reconnection. It is known that pure Ohmic decay is inefficient, occurring during cosmological times (due to the huge characteristic scales $L$). It is recognized that the presence of current sheets speeds up the process, but still insufficiently$^{1,2,3,4,5}$. We show that, in highly compressible and substantially gravitational media, the reconnection is fast enough to account for stormy events. Thus, highly compressible situations offer exiting opportunities in explanations of violent events, although full-scale compressible and gravitational simulations proved to be quite challenging.
