Abstract

The laboratory simulations of jets from young stars that have been carried out for many years at plasma focus facilities allow the internal structure of the active regions emerging during the interaction of the jet with the surrounding plasma to be studied in detail. We have found a new wide class of solutions for the equations of ideal magnetohydrodynamics describing the closed axisymmetric stationary flows that are apparently realized in the active regions. Such flows are shown to well reproduce the internal structure of the plasma outflows observed in laboratory simulations of astrophysical jets.

等离子聚焦设施模拟的年轻恒星喷射器的内部结构

摘要

在等离子体聚焦设备上进行了多年的年轻恒星射流的实验室模拟,可以详细研究射流与周围等离子体相互作用期间出现的活动区域的内部结构。我们已经找到了理想的磁流体动力学方程的一类新的宽解,描述了明显在活动区域​​中实现的闭合轴对称平稳流。这些流动被证明可以很好地再现在天体物理射流的实验室模拟中观察到的血浆流出的内部结构。
