极端质量比双星的解析高阶后牛顿展开式

Analytical high-order post-Newtonian expansions for extreme mass ratio binaries

Chris Kavanagh, Adrian C. Ottewill, Barry Wardell

摘要:

本文给出了围绕Schwarzschild黑洞的圆形轨道上的质点的规范不变量的解析计算,给出了15.5后牛顿阶的结果,在在线知识库中给出了21.5后牛顿阶的结果。我们的计算是基于Mano,Suzuki和Takasugi(MST)的函数级数方法和Bini和Damour最近的一系列结果。我们开发了一种优化的方法,用于生成MST系列的后牛顿展开式,从而实现更快的计算。我们还澄清了大值的$\ell$的扩展的结构,并在这样做开发一个有效的新方法产生的MST重整化角动量,$ν$。

英文摘要:

We present analytic computations of gauge invariant quantities for a point mass in a circular orbit around a Schwarzschild black hole, giving results up to 15.5 post-Newtonian order in this paper and up to 21.5 post-Newtonian order in an online repository. Our calculation is based on the functional series method of Mano, Suzuki and Takasugi (MST) and a recent series of results by Bini and Damour. We develop an optimised method for generating post-Newtonian expansions of the MST series, enabling significantly faster computations. We also clarify the structure of the expansions for large values of $\ell$, and in doing so develop an efficient new method for generating the MST renormalised angular momentum, $ν$.
