实验室天体物理的验证特例：W43A磁喷流

摘要

利用神光II号八路激光与平面Al靶相互作用产生双等离子体喷流。利用阿尔芬-欧拉磁流体动力学标度变换理论产生的喷流与天体环境下形成的W43A喷流进行比较。发现在实验室中直接测量的喷流物理量经过变换后，与天文观测数据极其相似，同时提出重联电场对喷流的形成与准直存在直接的影响。%Dual Al plasma jets are generated with eight Shenguang II lasers. With Euler MHD scale law we find that the jet produced in the laboratory is highly similar to astronomical observations after transformation. We propose that the reconnection electric filed should have a possible direct influence on the formation and collimation of the plasma jet.
