论文摘要
未来激光干涉仪空间天线可检测到的极端质量比率灵感，为测试一般相对论和基本物理学提供了独特的方法。在这种可能性的推动下，我们在这里详细研究了在旋转次要的情况下的EMRI动力学，收集和扩展了以前工作中出现的各种结果，并首次提供了有用的中间步骤和新的关系。我们介绍了计算重力波通量的频域代码的结果，以及带有（抗）对齐旋转的圆形赤道轨道的情况下的绝热轨道演变。次级的自旋开始与领先的自力义术语相同的绝热后秩序，并引入可检测到的dephasing，可用于以$ 5-25 \％$的水平进行测量，具体取决于单个旋转。在同伴论文中，我们讨论了这种效果对Kerr结合的测试的含义。
Extreme mass-ratio inspirals detectable by the future Laser Interferometer Space Antenna provide a unique way to test general relativity and fundamental physics. Motivated by this possibility, here we study in detail the EMRI dynamics in the presence of a spinning secondary, collecting and extending various results that appeared in previous work and also providing useful intermediate steps and new relations for the first time. We present the results of a frequency-domain code that computes gravitational-wave fluxes and the adiabatic orbital evolution for the case of circular, equatorial orbits with (anti)aligned spins. The spin of the secondary starts affecting the gravitational-wave phase at the same post-adiabatic order as the leading-order self-force terms and introduces a detectable dephasing, which can be used to measure it at $5-25\%$ level, depending on individual spins. In a companion paper we discuss the implication of this effect for tests of the Kerr bound.
