Exploiting simple yet remarkable properties of relativistic gravitational scattering, we use first-order self-force (linear-in-mass-ratio) results to obtain arbitrary-mass-ratio results for the complete third-subleading post-Newtonian (4.5PN) corrections to the spin-orbit sector of spinning-binary conservative dynamics, for generic (bound or unbound) orbits and spin orientations. We thereby improve important ingredients of models of gravitational waves from spinning binaries, and we demonstrate the improvement in accuracy by comparing against aligned-spin numerical simulations of binary black holes.

通过三阶次牛顿后阶的引力自旋轨道耦合：从一阶自力到任意质量比。

利用相对论引力散射的简单但引人注目的特性，我们使用一阶自力（质量比线性）结果来获得完整的第三副超牛顿后校正（4.5PN）的任意质量比结果。自旋二进制保守动力学的自旋轨道扇区，用于一般（有界或无界）轨道和自旋方向。因此，我们改进了自旋二元的引力波模型的重要组成部分，并且通过与二元黑洞的对准自旋数值模拟进行比较，证明了准确性的提高。
