论文摘要
二进制系统附近的第三个对象会导致偏心率的变化和二进制的倾斜度通过Kozai-Lidov效应。我们检查了这种变化是否在由中间质量黑洞和恒星质量物体组成的二进制的重力波上留下可检测的烙印。作为概念的证明，我们提出了一个例子，其中丽莎可以检测到这种来源的Kozai-Lidov调制引力信号，如果扰动是由超大质量的黑洞高等教育引起的，则至少从1MPC距离。尽管一般相对论引起的快速中心进液通过淬灭Kozai-Lidov振荡可显着降低这种效果的适当参数空间，但我们仍然找到合理的参数，在该参数中可以通过高信噪比检测到Kozai-Lidov效应。
A third object in the vicinity of a binary system causes variations in the eccentricity and the inclination of the binary through the Kozai-Lidov effect. We examine if such variations leave a detectable imprint on the gravitational waves of a binary consisting of intermediate mass black holes and stellar mass objects. As a proof of concept, we present an example where LISA may detect the Kozai-Lidov modulated gravitational wave signals of such sources from at least a distance of 1Mpc if the perturbation is caused by a supermassive black hole tertiary. Although the quick pericenter precession induced by general relativity significantly reduces the appropriate parameter space for this effect by quenching the Kozai-Lidov oscillations, we still find reasonable parameters where the Kozai-Lidov effect may be detected with high signal-to-noise ratios.
