Dynamics of Cometary Environments

AST 0098582 gombosidrs。密歇根大学的Tamas Gombosi和Michael Combi将继续一个彗星建模项目，这个项目的独特之处在于，它用最先进的数值模拟代码来解决彗星昏迷现象的全部范围。这些研究人员有将这些代码直接应用于观察结果分析的经验。模型的进一步发展将受益于计算机能力的快速扩展和使多维仿真技术得以应用的高性能算法。该项目的长期目标是开发和应用一个多尺度、自一致的彗星大气综合模型，从复杂的三维核心延伸到数千万公里外的彗发和彗尾。＊＊＊

AST 0098582GombosiDrs. Tamas Gombosi and Michael Combi, at the University of Michigan, will continue a comet modeling project that is unique in that it addresses the full range of cometary coma phenomena with state-of-the-art numerical simulation codes. These investigators have experience in applying these codes directly to the analysis of observations. Further development of the models will benefit from the rapid expansion in capabilities of computers and high performance algorithms enabling multi-dimensional simulation techniques to be applied. The long term goal for this project is the development and application of a multi-scale, self-consistent comprehensive model of atmospheres of comets, extending from the complex 3-D nucleus to tens of millions of kilometers into the outer coma and tail. ***
