论文摘要
混乱的三体相互作用可能导致引力波的形成。在这里,通过将相遇建模为一系列紧密的,非分层的三重方法,散布在分层阶段中,该系统由内部二进制和恒星绕着它组成,我们计算了周围的概率分布,从而在任何给定的二进制二进制二进制中的近距离遇到了旁心概率。然后,我们通过改变簇中硬二进制的偏心分布来考虑二进制遇到对重力波源种群的间接影响;我们通过要求在与单星星的相互作用下进行分析计算该分布。
Chaotic three-body interactions may lead to the formation of gravitational-wave sources. Here, by modelling the encounter as a series of close, non-hierarchical, triple approaches, interspersed with hierarchical phases, in which the system consists of an inner binary and a star that orbits it, we compute the pericentre probability distribution, and thereby the in-spiral probability in any given binary-single encounter. We then consider the indirect influence of binary-single encounters on the population of gravitational-wave sources, by changing the eccentricity distribution of hard binaries in clusters; we calculate this distribution analytically, by requiring that it be invariant under interactions with single stars.
