论文摘要
`OUMUAMUA和BORISOV是太阳系中确认的前两个星际对象。 Vera C. Rubin天文台对时间空间（LSST）的遗产调查的即将开始，将大大提高星际物体的发现率。这就提出了一个问题，可以从星际对象的大数字统计数据中学到什么？在这里，我们表明，LSST提供的发现统计量将允许使用星际对象的速度分散和角度各向异性区分低次数和高质量速度种群。这些发现可以与身体特征结合在一起，以更好地了解行星系统的起源和自然。
`Oumuamua and Borisov were the first two interstellar objects confirmed in the Solar system. The upcoming commencement of the Vera C. Rubin Observatory's Legacy Survey of Space of Time (LSST) will enhance greatly the discovery rate of interstellar objects. This raises the question, what can be learned from large-number statistics of interstellar objects? Here, we show that discovery statistics provided by LSST will allow low- and high-ejection-speed populations to be distinguished using the velocity dispersion and angular anisotropy of interstellar objects. These findings can be combined with physical characterizations to yield a better understanding of planetary system origin and nature.
