The Nonlinear Dynamics of Quasi-Collisional Neutral Gases inthe Solar System (A Case Study of the Triton Tori)

AST-9619629太阳系中准碰撞中性气体的非线性动力学(以Triton环面为例)。马可尼博士将对海王星环的物理进行详细而严谨的理论研究。海王星环是围绕海王星的一个气体环，由海王星最大的卫星提供。这项研究应该会产生一个真实的海王星环面模型，这将对其他对海王星和海王星磁层感兴趣的研究小组有用。该项目有三个相互交织的目标。第一个目标是从一般意义上加强对太阳系中准碰撞气体环的非线性动力学的理论理解。第二个目标是提供准碰撞Triton原子氢、分子氢和氮环的特定气体模型，并评估它们对海王星磁层的影响。第三个目标是通过所有动力学机制扩大和加强对天体物理气体的研究，并制定一致的数值方案来描述它们。=

AST-9619629 The Nonlinear Dynamics of Quasi-Collisional Neutral Gases in the Solar System (A Case Study of the Triton Tori). Dr. Marconi will carry out a detailed and rigorous theoretical investigation of the physics of the Triton torus, a gas ring around Neptune fed by its largest satellite. This research should lead to a realistic model of the Triton tori which will be of use to other research groups interested in Triton and Neptune's magnetosphere. The project has three intertwined objectives. The first objective is to enhance in a general sense the theoretical understanding of the nonlinear dynamics of quasi- collisional gas tori in the Solar System. The second objective is to provide a specific gas model of the quasi-collisional Triton atomic hydrogen, molecular hydrogen, and nitrogen tori and evaluate their effects on the Neptune magnetosphere. The third objective is to broaden and enhance the study of astrophysical gases through all kinetic regimes and to develope consistent numerical schemes to describe them. ====================================
