Bell非共振Cosmic Ray不稳定性模型
Modeling Bell's Non-resonant Cosmic Ray Instability
摘要:
我们研究了Bell(2004)发现的带电高能粒子在背景等离子体中运动的非共振流不稳定性。我们证实了他的数值计算结果关于一个显着的磁场放大系统。给出了不稳定性发展和磁场演化的详细物理图象。
英文摘要:
We have studied the non-resonant streaming instability of charged energetic particles moving through a background plasma, discovered by Bell (2004). We confirm his numerical results regarding a significant magnetic field amplification in the system. A detailed physical picture of the instability development and of the magnetic field evolution is given.
