论文摘要
星际对象的局部检测率可以估算由银河系薄磁盘绑定的相似对象的总数。如果发现了人工来源的星际对象,则估计的对象总数可能会降低约$ 10^{16} $,如果它们针对太阳周围的可居住区。我们提出了一个模型,用于根据对象的速度和观察到的密度来计算感兴趣的天然或人工星际对象的数量。然后,我们将该模型应用于外星文明的化学推进火箭案的情况。最后,我们将模型应用于先前发现的三个星际对象 - 未知来源的对象'OUMUAMUA和第一个星际流星Cneos Cneos 2014-01-08和Cneos 2017-03-09。
The local detection rate of interstellar objects can allow for estimations of the total number of similar objects bound by the Milky Way thin disk. If interstellar objects of artificial origin are discovered, the estimated total number of objects can be lower by a factor of about $10^{16}$ if they target the habitable zone around the Sun. We propose a model for calculating the quantity of natural or artificial interstellar objects of interest based on the object's velocity and observed density. We then apply the model to the case of chemically propelled rockets from extraterrestrial civilizations. Finally, we apply the model to three previously discovered interstellar objects -- the object 'Oumuamua of unknown origin and the first interstellar meteors CNEOS 2014-01-08 and CNEOS 2017-03-09.
