我们将Schwarzschild时空中detweiler - bark - sago红移不变量的偏心率扩展的解析知识提高到$e^2$和$e^4$贡献的9.5阶后牛顿阶(包括),并通过$e^{20}$提高到更高偏心率贡献的4阶后牛顿阶。我们将这些信息转换为通过9.5阶后牛顿阶的有效单体径向势$\bar d(u)$, $\rho(u)$和$q(u)$的分析知识。我们发现我们的分析结果与目前相应的数值自力数据是一致的。
We raise the analytical knowledge of the eccentricity-expansion of the Detweiler-Barack-Sago redshift invariant in a Schwarzschild spacetime up to the 9.5th post-Newtonian order (included) for the $e^2$ and $e^4$ contributions, and up to the 4th post-Newtonian order for the higher eccentricity contributions through $e^{20}$. We convert this information into an analytical knowledge of the effective-one-body radial potentials $\bar d(u)$, $\rho(u)$ and $q(u)$ through the 9.5th post-Newtonian order. We find that our analytical results are compatible with current corresponding numerical self-force data.
