具有四极矩校正的增强解析组合波形

Augmented analytic kludge waveform with quadrupole moment correction

Miaoxin Liu, Jian-dong Zhang

摘要:

EMRI是未来天琴、LISA等星载引力波探测器的重要光源之一。它发生在星系中心的大质量黑洞周围的恒星源致密天体,在天体物理和基础理论研究中有许多好处。最重要的目标之一是通过测量MBH的四极矩来检验无毛定理。这就要求我们对EMRI系统的参数进行足够精确的估计,这意味着我们还需要一个精确的波形模板。基于标准Kerr黑洞的快速、基准增广解析kludge(AAK)波形,我们建立了一个非Kerr四极矩度规的波形模型.我们还分析了不同的源和检测器的参数估计的精度。

英文摘要:

One of the most important sources for future space-borne gravitational wave detectors such as TianQin and LISA is EMRI. It happens when a stellar orgin compact object orbiting around a massive black hole(MBH) in the center of galaxies and has many benefits in the study of astrophysics and fundamental theories. One of the most important objectives is to test the no-hair theorem by measuring the quadrupole moment of the MBH. This requires us to estimate the parameters of an EMRI system accurately enough, which means we also need an accurate waveform templet for this process. Based on the fast and fiducial augmented analytic kludge (AAK) waveform for the standard Kerr black hole, we develop a waveform model for a metric with non-Kerr quadrupole moment. We also analyze the accuracy of parameter estimation for different sources and detectors.
