论文摘要
我们计算出高牛顿后精度的4个弹药（线性动量和能量），在两体系统中被重力散射的两体系统中的重力波辐射。我们首次将所有相关的{\ it时间 - 对称}效应包括在牛顿领先后的牛顿后订单之外时始终如一。我们发现，包括时间 - 对称辐射效应（在尾部和辐射反应双曲运动中）对于确保辐射4 Momentum的胶后扩张（$ g $膨胀）的大量顺式对线性至关重要。施加相应个体冲动的质量顺序性，确定了第四次米科夫斯基秩序中的保守辐射贡献，并在第五次后 - 康科夫斯基秩序上强烈限制了它们。
We compute to high post-Newtonian accuracy the 4-momentum (linear momentum, and energy), radiated as gravitational waves in a two-body system undergoing gravitational scattering. We include, for the first time, all the relevant {\it time-asymmetric} effects that arise when consistently going three post Newtonian orders beyond the leading post Newtonian order. We find that the inclusion of time-asymmetric radiative effects (both in tails and in the radiation-reacted hyperbolic motion) is crucial to ensure the mass-polynomiality of the post-Minkowskian expansion ($G$ expansion) of the radiated 4-momentum. Imposing the mass-polynomiality of the corresponding individual impulses determines the conservativelike radiative contributions at the fourth post-Minkowskian order, and strongly constrains them at the fifth post-Minkowskian order.
