太阳系尘埃动力学研究综述

Review of research on Solar System dust dynamics

太阳系尘埃动力学是一个比较新的研究方向,对理解太阳系起源、演化以及指导航天探测任务都有重要意义。该文对近几十年来太阳系尘埃动力学方面的研究进行了综述。关于尘埃的质量产率和撞击-喷射这一尘埃起源方式,介绍了前人基于地面实验结果而建立的模型,以及基于就位探测和实验得到的初始质量分布。同时,回顾了关于尘埃所受主要摄动力的建模方面的工作,以及经常用到的一些辅助分析方法。此外,尘埃的充电和溅射都会影响其动力学行为,也介绍了相关的建模和实验研究。最后,总结了尘埃族群具有代表性的形成/迁移机制,以及这些机制对尘埃族群分布构型的影响。

Solar System dust dynamics is a relatively new research topic which is important for understanding the origin and evolution of the Solar System as well as for space missions.This paper presents a review of recent studies on Solar System dust dynamics.The dust mass production model based on experiments by previous research for the impact-ejected process is introduced,and the initial mass distribution inferred from the in-situ detections and experiments is shown.This paper also reviews research on the modelling of perturbation forces and commonly used analytical methods.Modelling and experimental studies are presented for both dust charging and sputtering effects which affect the particle dynamics.Finally,the typical formation/migration mechanisms of particle populations as well as their significance on the dust distributions are summarized.
