我们可以检测中间质量比吸气吗?

Can we Detect Intermediate Mass Ratio Inspirals?

Ilya Mandel, Jonathan R. Gair

摘要:

在中等质量黑洞(IMBH)进入超大质量黑洞的中等质量比吸入(IMRI)过程中发射的引力波可能是LISA的一个非常有趣的来源。类似地,恒星质量的紧凑物体进入IMBH的IMRI可以被先进的LIGO探测到。然而,目前还不清楚什么波形可以用于IMRI检测,因为后牛顿近似打破了IMRI接近最内部的稳定圆形轨道,微扰解只知道最低阶的质量比。我们讨论了近似波形和真实波形之间的预期失配,以及作为质量比和系统总质量的函数的最佳可用波形的选择。我们还评论的意义上的自旋较小的机构和需要将其列入波形。

英文摘要:

Gravitational waves emitted during intermediate-mass-ratio inspirals (IMRIs) of intermediate-mass black holes (IMBHs) into supermassive black holes could represent a very interesting source for LISA. Similarly, IMRIs of stellar-mass compact objects into IMBHs could be detectable by Advanced LIGO. At present, however, it is not clear what waveforms could be used for IMRI detection, since the post-Newtonian approximation breaks down as an IMRI approaches the innermost stable circular orbit, and perturbative solutions are only known to the lowest order in the mass ratio. We discuss the expected mismatches between approximate and true waveforms, and the choice of the best available waveform as a function of the mass ratio and the total mass of the system. We also comment on the significance of the spin of the smaller body and the need for its inclusion in the waveforms.
