论文摘要
Oort云和分散的磁盘分别是长期和短周期彗星的两个主要储层。在这篇综述中，我们评估了这些储层特性及其形成的已知观察性约束。此外，我们讨论了巨型行星的早期轨道演变如何从早期的大型行星磁盘中产生现代散射的磁盘，以及如何将此材料的$ \ sim $ 5 \％捕获到Oort云中。我们回顾一下银河系中太阳的出生环境和动态历史如何改变欧特云的形成和现代结构。最后，我们评估未来十年的预期观察活动如何为Oort云和分散磁盘的形成和特性提供新的见解。
The Oort cloud and the scattered disk are the two primary reservoirs for long-period and short-period comets, respectively. In this review, we assess the known observational constraints on these reservoirs' properties and their formation. In addition, we discuss how the early orbital evolution of the giant planets generated the modern scattered disk from the early, massive planetesimal disk and how $\sim$5\% of this material was captured into the Oort cloud. We review how the Sun's birth environment and dynamical history within the Milky Way alters the formation and modern structure of the Oort cloud. Finally, we assess how the coming decade's anticipated observing campaigns may provide new insights into the formation and properties of the Oort cloud and scattered disk.
