Dynamical structure and evolution of the young solar system

这项工作将进行理论分析和数值模拟，以研究太阳系早期巨行星迁移对太阳系内轨道动力学的影响。PI及其团队将研究近地天体（NEO）角轨道要素的非均匀分布，计算具有不同轨道结构的内太阳系的长期动力学，对巨行星迁移影响下的此类结构的稳定性进行数值模拟，并计算LHB前小行星库的损失率，以及对行星上大撞击通量的估计。这项工作的更广泛影响包括对太阳系外行星系统的应用，碎片盘和地球的气候历史。这项工作对早期太阳系的形成和发展具有影响，有助于了解近地天体的数量，其中有些可能对地球构成危险，并有助于建立围绕其他恒星的行星系统的模型。 这项工作将涉及博士学位。论文和PI将为公众观众制作一个关于这项工作的幻灯片演示，免费提供。

This work will conduct theoretical analysis and numerical simulations to study the inner solar system orbital dynamics that were affected by giant planet migration during the early solar system. The PI and her team will investigate the non-uniform distribution of the angular orbital elements of Near-Earth-Objects (NEOs), calculate the secular dynamics of the inner solar system with different orbital architectures, carry out numerical simulations of the stability of such architectures under the effects of giant planet migration, and calculate the loss rates from the pre-LHB asteroid reservoirs and estimates of the flux of large impacts on the planets.Broader impacts of the work include applications to extrasolar planetary systems, debris disks and the Earth's climate history. This works has implications for the formation and development of the early solar system, is relevant to understanding the population of NEOs, some of which may be hazardous to Earth, and to modeling the planetary systems around other stars. The work will be involved in a Ph.D. dissertation and the PI will produce a slide presentation on this work for public audiences, made available for free.
