论文摘要
在本文中，在极端的质量比率Inspiral的背景下，我们讨论了晚期的灵感启发性，然后讨论了次要的，不太紧凑的物体的过渡阶段。在存在于极端质量比率系统的较高时空尺寸的潮汐电荷的情况下，我们获得了由于缓慢发展的运动常数（例如能量和角动量）而获得的通量的近似表达。这些通量的表达式进一步用于引入耗散效应，同时通过过渡制度对跌落阶段进行建模。在我们的设置中，我们对Braneworld场景中存在的额外潮汐充电如何通过增强过渡制度的时间尺度来影响爆发的时间尺度，从而提供定性的理解。最后，我们利用从引力波检测器从晚期灵感到跌落的过渡状态的可观察到的过渡状态的可观察到的潮汐电荷进行了估计。
In the present article, we discuss the late inspiral and then the transition regime to the plunge phase of a secondary, less massive compact object into a more massive braneworld black hole, in the context of an extreme-mass-ratio inspiral. We obtain the approximate expressions for fluxes due to slowly evolving constants of motion, such as the energy and the angular momentum, in the presence of the tidal charge inherited from the higher spacetime dimensions for an extreme-mass-ratio system. These expressions for fluxes are further used to introduce dissipative effects while modeling the inspiral to the plunge phase through the transition regime. Within our setup, we provide a qualitative understanding of how the additional tidal charge present in the braneworld scenario may affect the timescale of the late inspiral to the plunge, in particular, by enhancing the time scale of the transition regime. Finally, we provide an estimate for the tidal charge from the higher dimensions, using the observable aspects of the transition regime from the late inspiral to the plunge by the gravitational wave detectors.
