AST-0907972LewisThis project supports two students to work on numerical investigations of planetary systems involving collisional dynamics, primarily planetary ring dynamics and planetary formation, including enhancement of the codes used. This project is funded under the auspices of the Research in Undergraduate Institutions (RUI) program. The Principal Investigator is working on simulation of the Saturnian ring system and on a general data analysis and visualization tool, with support from the National Aeronautics and Space Administration (NASA). This added-value project will significantly improve the research as well as strengthen the existing collaboration, while including undergraduate students on a cutting-edge project in planetary science.One student will work to organize and perform simulations of embedded moonlets, silicate material in the ring, and Saturn's F ring, and to analyze the results. The second student will work to improve the simulation code by enhancing support for accretion, and to develop analysis tools for the code. Their results will aid in interpreting Cassini observations and providing a general understanding of the Saturnian ring system, as well as helping to understand the early stages of planetary accretion. Comparison with experiments will enhance the accuracy of these numerical models, and improve the quality of the tools available to the whole planetary science community. The students will also present their results each year at an astronomy conference and at a conference on parallel computing or simulation methodologies.

这个项目支持两个学生从事行星系统的数值研究，包括碰撞动力学，主要是行星环动力学和行星形成，包括对所用代码的改进。该项目是由本科院校研究(RUI)项目资助的。首席调查员在美国国家航空航天局(美国航天局)的支持下，正在模拟土星环系统，并开发一种通用的数据分析和可视化工具。这个具有附加值的项目将显著改善研究并加强现有的合作，同时包括行星科学尖端项目的本科生。一名学生将组织和执行嵌入月球的小行星、光环中的硅酸盐材料和土星的F环的模拟，并分析结果。第二个学生将通过增强对增长的支持来改进模拟代码，并为代码开发分析工具。他们的结果将有助于解释卡西尼号的观测结果，提供对土星环系的总体理解，以及有助于理解行星吸积的早期阶段。与实验的比较将提高这些数值模型的准确性，并提高整个行星科学界可用的工具的质量。这些学生还将在每年的天文学会议和关于并行计算或模拟方法的会议上展示他们的成果。
