我们研究外部磁场存在下的球形无碰撞冲击。球形无碰撞激波是膨胀等离子体与周围等离子体（例如太阳风、恒星风和超新星遗迹）之间相互作用的常见结果。在冲击传播及其发射中经常观察到各向异性，人们普遍认为磁场起着主要作用。由于无法对天体物理等离子体中的磁场进行局部观测，因此实验室实验提供了研究此类现象的独特能力。我们通过在磁场存在的情况下照射被等离子体包围的固体球形目标来模拟宇宙中的球形冲击。我们展示通过阴影摄影术获得的初步结果。
We investigate spherical collisionless shocks in the presence of an external magnetic field. Spherical collisionless shocks are common resultant of interactions between a expanding plasma and a surrounding plasma, such as the solar wind, stellar winds, and supernova remnants. Anisotropies often observed in shock propagations and their emissions, and it is widely believed a magnetic field plays a major role. Since the local observations of magnetic fields in astrophysical plasmas are not accessible, laboratory experiments provide unique capability to investigate such phenomena. We model the spherical shocks in the universe by irradiating a solid spherical target surrounded by a plasma in the presence of a magnetic field. We present preliminary results obtained by shadowgraphy.
