Analysis of Microwave Interferometer Observations of Jupiter During Impact with Comet Shoemaker-Levy 9

作为美国国家科学基金会资助的关于1994年7月苏梅克-列维9号彗星撞击木星后续研究的一部分，格罗斯曼博士和他的联合首席研究员约翰·王博士将完成对独特的无线电干射仪观测数据集的简化和分析，这些数据集用于确定撞击期间和之后该事件对木星对流层和磁层的影响。这些数据集是由甚大阵列和澳大利亚望远镜获得的。特别是，研究人员希望获得大气结构和微量成分（氨、硫化氢和水）丰度的信息；与影响有关的可辨别的特征是否存在；以及每个碎片的穿透深度。此外，这项研究有望提高我们对木星磁层对尘埃加载和冲击的响应，以及注入物质的输运和各种物理扰动的弛豫的时间尺度的理解。**

95-26305 Grossman As part of NSF-funded follow-up studies of the Comet Shoemaker-Levy 9 impact on Jupiter in July 1994, Dr. Grossman and his co-principal investigator, Dr. John Wang, will complete the reduction and analysis of unique radio interferometer observational data sets, which were taken to determine the effects the event had on the Jovian troposphere and magnetosphere during and after the impact. The data sets were obtained at the Very Large Array and the Australia Telescope. In particular, the investigators expect to get information on atmospheric structure and the abundances of the trace constituents ammonia, hydrogen sulfide, and water; the presence or lack of discernible features associated with the impacts; and the penetration depths of the individual fragments. Furthermore, this research is expected to improve our understanding of the response of the Jovian magnetosphere to dust loading and shocking, and the time-scales for transport of injected material and relaxation of the various physical perturbations. **
