在引力波传播的非线性的印记-尾部效应-是负责新的自旋贡献的能量通量和旋转黑洞双星的轨道定相。自旋-轨道（自旋线性）对这种效应的贡献目前已知在领先的后牛顿（PN）阶，即3 PN的最大自旋黑洞在准圆形轨道上。在目前的工作中，我们推广这些尾部起源的自旋轨道项的下一个领先的4PN顺序。这需要特别是扩展以前的结果的动态演变的进动紧凑的二进制文件。我们表明，尾巴代表唯一的自旋轨道项在该顺序的准圆轨道，我们发现完美的协议与已知的结果为测试粒子围绕克尔黑洞，微扰理论计算。BH层吸收项必须加到这里计算的PN结果中。我们的工作完成的知识的自旋轨道效应的相位的紧凑的二进制到4PN顺序，并允许建立更忠实的PN模板的黑洞二进制的inspiral阶段，提高地基和天基引力波探测器的能力。
The imprint of nonlinearities in the propagation of gravitational waves—the tail effect—is responsible for new spin contributions to the energy flux and orbital phasing of spinning black hole binaries. The spin–orbit (linear in spin) contribution to this effect is currently known at leading post-Newtonian (PN) order, namely 3PN for maximally spinning black holes on quasi-circular orbits. In the present work, we generalize these tail-originated spin–orbit terms to the next-to-leading 4PN order. This requires in particular extending previous results on the dynamical evolution of precessing compact binaries. We show that the tails represent the only spin–orbit terms at that order for quasi-circular orbits, and we find perfect agreement with the known result for a test particle around a Kerr black hole, computed by perturbation theory. The BH-horizon absorption terms have to be added to the PN result computed here. Our work completes the knowledge of the spin–orbit effects to the phasing of compact binaries up to the 4PN order, and will allow the building of more faithful PN templates for the inspiral phase of black hole binaries, improving the capabilities of ground-based and space-based gravitational wave detectors.
