This project will examine whether the recently-developed theory of BGK (Bernstein-Greene-Kruskal) wave modes in a magnetized plasma can account for the unusual features of electrostatic bursts (ESBs) observed in magnetospheric chorus waves in the outer magnetosphere and magnetospheric cusp of the Earth as well as the magnetospheres of Jupiter and Saturn. The ESB events can be quite large and understanding the source mechanism is likely to be relevant to processes that affect the radiation belts and the work thus has relevance to understanding and predicting space weather. The project will extend the BGK nonlinear theory and will compare the results with ESB events observed from a variety of satellite missions.

该项目将检查磁化等离子体中最近发达的BGK（Bernstein-Greene-kruskal）波模式是否可以解释磁层合唱波在外部磁圈和地球层的磁层层中观察到的静电层爆发（ESB）的异常特征（ESB）。 ESB事件可能很大，了解源机制可能与影响辐射带的过程有关，因此工作与理解和预测空间天气有关。该项目将扩展BGK非线性理论，并将结果与​​从各种卫星任务中观察到的ESB事件进行比较。
