论文摘要
分层2+2配置中的一些四颗星系统在两个紧凑的二进制室之间表现出轨道 - 轨道共振。我们表明，最重要的共振以1：1、3：2和2：1的周期比出现。我们描述了捕获所需的条件，并表明它们可以在二进制的3：2和2：1的共振中得到满足，这些二进制的共振可能通过磁制动或重力辐射在圆形后轴轴上显着迁移。
Some quadruple star systems in the hierarchical 2+2 configuration exhibit orbit-orbit resonances between the two compact binaries. We show that the most important resonances occur at period ratios of 1:1, 3:2 and 2:1. We describe the conditions required for capture and show that they can be satisfied at the 3:2 and 2:1 resonances in binaries that migrate significantly in semimajor axis after circularization, probably through magnetic braking or gravitational radiation.
