观测LISA中双黑洞的偏心振荡

Observing Eccentricity Oscillations of Binary Black Holes in LISA

Lisa Randall, Zhong-Zhi Xianyu

摘要:

来自双星系统附近的第三个天体的潮汐力可以在双星的偏心率中引入长期振荡,称为Kozai-Lidov振荡。我们证明了恒星质量黑洞双星的Kozai-Lidov振荡具有被LISA观测到的潜力。对这类双星的探测将有助于深入了解双星的形成通道,并为直接观测Kozai-Lidov振荡提供重要的基准。

英文摘要:

The tidal force from a third body near a binary system could introduce long-term oscillations in the binary's eccentricity, known as Kozai-Lidov oscillations. We show that the Kozai-Lidov oscillations of stellar-mass black hole binaries have the potential to be observed by LISA. Detections of such binaries will give insights into binary formation channels and also provide an important benchmark of observing Kozai-Lidov oscillations directly.
