Plasma Physics of the Geomagnetic Tail

磁层的一个关键区域是 磁尾被认为是 磁层亚暴，这是时间间隔， 伴随着洋流的增强和 极光（即北方光）。 该补助金集中在三个 关于磁尾等离子体物理学的问题： 中频静电等离子体波的起源，2） 闭合磁场中的无碰撞撕裂模重联 等离子体片的场线区域，以及3） 在遥远的尾部产生无碰撞冲击。 这些问题将 附加使用观察，分析理论和数值 仿真。

One of the critical regions of the magnetosphere is the magnetotail, which is thought to be responsible for magnetospheric substorms, which are intervals of time that are associated with enhanced currents and intensification of the auroral (i.e. northern lights). This grant concentrates on three problems concerning the plasma physics of the magnetotail: 1) the origin of mid-frequency electrostatic plasma waves, 2) collisionless tearing mode reconnection in teh closed magnetic field-line region of the plasma sheet, and 3) the structure of collisionless shocks in the distant tail. These problems will be attached using observations, analytic theory and numerical simulations.
