论文摘要
我们提出了一个新的方便框架，用于对Reissner-Nordström黑洞的重新分布进行建模。使用此框架，我们量化了如果一个或两个组件被充电，则如何影响紧凑型二元系统的重力波观测。我们的方法通过便利的主功能来简化（线性化的）爱因斯坦 - 马克斯韦尔方程，我们旨在改善先前策略的某些缺点。通过用点源求解我们改进的主方程，我们可以通过电磁和重力辐射来量化轨道能量耗散的速率。通过绝热和绝热近似值，我们应用耗散计算来确定中间和极端质量比率灵感的轨迹。通过将带有多种电荷的轨迹和波形与中性成分的轨迹和波形进行比较，我们探讨了电荷对重力波信号的潜在影响。我们观察到，相反的电荷与质量比率具有最大的影响。我们的发现在很大程度上是通过即将到来的丽莎任务的镜头来解释的。
We present a new convenient framework for modeling Reissner-Nordström black hole perturbations from charged distributions of matter. Using this framework, we quantify how gravitational wave observations of compact binary systems would be affected if one or both components were charged. Our approach streamlines the (linearized) Einstein-Maxwell equations through convenient master functions that we designed to ameliorate certain disadvantages of prior strategies. By solving our improved master equations with a point source, we are able to quantify the rate of orbital energy dissipation via electromagnetic and gravitational radiation. Through adiabatic and quasicircular approximations, we apply our dissipative calculations to determine trajectories for intermediate and extreme mass-ratio inspirals. By comparing trajectories and waveforms with varied charges to those with neutral components, we explore the potential effect of electric charge on gravitational wave signals. We observe that the case of opposite charge-to-mass ratios has the most dramatic impact. Our findings are largely interpreted through the lens of the upcoming LISA mission.
