论文摘要
由于引力波检测器的灵敏度显着进步,引力波的迅速发展,这使得能够检测到二进制黑洞合并的检测前景。极端质量比Inspiral(EMRI)是朝这个方向上最引人注目,最迷人的二进制系统之一,而未来的基于空间的重力波检测器的检测可能性。在本文中,我们考虑了一个EMRI系统,其中主对象或中心对象是球形对称的静态braneworld黑洞,它带有\ textIt {tidal Charge} $ q $。我们估计潮汐电荷对无旋转次级辅助启发主要引起的总重力波通量和轨道相的影响。我们进一步强调了EMRI波形中潮汐电荷的观察意义。我们表明,丽莎(激光干涉仪空间天线)观察结果比黑洞阴影和基于地面的重力波观测可以对此参数产生更强的限制,这可能会探究额外维度的存在。
The field of gravitational waves is rapidly progressing due to the noticeable advancements in the sensitivity of gravitational-wave detectors that has enabled the detection prospects of binary black hole mergers. Extreme mass ratio inspiral (EMRI) is one of the most compelling and captivating binary systems in this direction, with the detection possibility by the future space-based gravitational wave detector. In this article, we consider an EMRI system where the primary or the central object is a spherically symmetric static braneworld black hole that carries a \textit{tidal charge} $Q$. We estimate the effect of the tidal charge on total gravitational wave flux and orbital phase due to a non-spinning secondary inspiralling the primary. We further highlight the observational implications of the tidal charge in EMRI waveforms. We show that LISA (Laser Interferometer Space Antenna) observations can put a much stronger constraint on this parameter than black hole shadow and ground-based gravitational wave observations, which can potentially probe the existence of extra dimensions.
