柯伊伯带碰撞的物理效应

Physical effects of collisions in the Kuiper belt

Zoe M. Leinhardt, Sarah T. Stewart, Peter H. Schultz

摘要:

碰撞是柯伊伯带历史上的一个主要修改过程。最近的工作阐明了个体碰撞到多孔、易挥发的物体上可能产生的复杂结果。这种碰撞对柯伊伯带天体的表面特征、组成和内部结构的累积影响尚不清楚。在这一章中,我们提出了目前的知识状态的物理学的陨石坑和破坏性碰撞KBO模拟材料。我们总结了柯伊伯带丰富的碰撞历史的证据,并提出了对个别对象的范围可能的物理修改。现今天体如何代表原始星子的问题可以通过未来柯伊伯带天体的耦合物理和碰撞演化的研究来解决。

英文摘要:

Collisions are a major modification process over the history of the Kuiper Belt. Recent work illuminates the complex array of possible outcomes of individual collisions onto porous, volatile bodies. The cumulative effects of such collisions on the surface features, composition, and internal structure of Kuiper Belt Objects are not yet known. In this chapter, we present the current state of knowledge of the physics of cratering and disruptive collisions in KBO analog materials. We summarize the evidence for a rich collisional history in the Kuiper Belt and present the range possible physical modifications on individual objects. The question of how well present day bodies represent primordial planetesimals can be addressed through future studies of the coupled physical and collisional evolution of Kuiper Belt Objects.
