9400202 Shemansky The PIs propose to examine theory for the consequences of the encounter of comet Shoemaker-Levy 9 with the Jupiter system. The purpose is twofold: (1) the Jupiter environment may provide a unique insight into the composition, structure and physical chemistry of SL9 through the expected enhanced extraction of the atomic and molecular components of the solid into the magnetosphere through sputtering and desorption in the inner and outer regions, and heating of the grains in the Io torus, and (2) the transient introduced into the magnetosphere may be strong enough to allow an unprecedented exploration of the intrinsic source and diffusive loss processes controlling the undisturbed planetary system. Predictive abilities include established model codes that are utilized to calculate the detailed emission properties of atomic and molecular species excited by physical chemistry as well as the combined direct processes of electron and photon excitation. ***

[4002 .]谢曼斯基PIs提议对苏梅克-列维9号彗星与木星系统相遇的结果进行理论检验。其目的是双重的：(1)木星环境可能为SL9的组成、结构和物理化学提供一个独特的视角，通过内部和外部区域的溅射和解吸，以及木卫一环面颗粒的加热，固体的原子和分子成分将被增强提取到磁层中。(2)引入磁层的瞬态可能足够强，可以对控制未受干扰的行星系统的内在源和扩散损失过程进行前所未有的探索。预测能力包括已建立的模型代码，用于计算物理化学激发的原子和分子物种的详细发射特性，以及电子和光子激发的联合直接过程。＊＊＊
