The need for more and more accurate gravitational wave templates requires taking into account all possible contributions to the emission of gravitational radiation from a binary system. Therefore, working within a multipolar-post-Minkowskian framework to describe the gravitational wave field in terms of the source multipole moments, the dominant instantaneous effects should be supplemented by hereditary contributions arising from nonlinear interactions between the multipoles. The latter effects are referred to as tails being described in terms of integrals depending on the past history of the source. We compute higher-order tail (i.e., tail-of-tail and tail-squared) contributions to both energy and angular momentum fluxes and their averaged values along hyperboliclike orbits at the leading post-Newtonian approximation, using harmonic coordinates and working in the Fourier domain. Due to the increasing level of accuracy recently achieved in the determination of the scattering angle in a two-body system by several complementary approaches, the knowledge of these terms will provide useful information to compare results from different formalisms.

在描述相对论性两体相互作用时,除了由于引力辐射的发射而导致的能量和角动量损失的影响外,还必须考虑线性动量的损失,这是系统质心反冲的原因。我们计算高阶尾(即,尾尾和尾平方)的贡献的线性动量通量的非自旋双星系统沿双曲线或椭圆形轨道。相应的轨道平均值在其领先的后牛顿近似下进行评估,使用调和坐标并在傅立叶域中工作。最后给出了沿双曲轨道的大偏心率(或大角动量)展开式和沿椭圆轨道的小偏心率展开式。因此,我们完成了先前的分析,重点是能量和角动量损失[Phys. Rev. D \textbf{104},no.10,104020(2021)],提供了有用的砖型结果,例如,用于高精度地确定经历散射过程的两个物体的辐射脉冲。
