柯伊伯带尘埃动力学研究进展

Progress of Research on Kuiper Belt Dust Dynamics

回顾了针对柯伊伯带开展的空间探测任务,介绍了柯伊伯带尘埃的2类形成机理和3类破坏机理。在此基础上,总结了前人在柯伊伯带尘埃动力学建模方面所做的工作,探讨了柯伊伯带尘埃表现出的族群迁移机制,以及柯伊伯带尘埃对于内太阳系行星际尘埃的贡献。研究有助于理解太阳系边际与星际空间的尘埃环境,从空间环境安全角度为太阳系边际探测任务的轨道设计提供一定的指导意义。

This paper reviews the recent research on the Kuiper Belt dust dynamics.Specifically,we review the related space exploration missions,introduce the origin and destruction mechanism of the Kuiper Belt dust,summarize previous studies on the modeling of the Kuiper Belt dust dynamics,and discuss the population migration mechanism as well as the contribution of Kuiper Belt dust to interplanetary dust in the inner solar system.This study helps to understand the dust environment in the solar system boundary and the interstellar space,and provide valuable insights for the orbital design of solar system boundary missions from the perspective of space environmental safety.
