引力波的尾部是由线性波散射到由源的总质能产生的时空曲率上引起的。很自然地，波尾的尾部是由波尾本身的曲率散射引起的。尾的尾部与两个质量矩之间的立方非线性相互作用有关，主要是源的质量四极矩。在本文中，我们确定在大距离的辐射场的源，这种特殊的双极-双极-四极相互作用。我们发现，尾巴的尾巴出现在第三后牛顿（3 PN）的订单超出通常的四极辐射。出于对未来引力波探测器的数据分析中所使用的精确模板的需要，我们计算的贡献的尾巴，尾巴的尾巴，到3.5PN的顺序所产生的能量通量的in-spiralling紧凑的双星。
The tails of gravitational waves are caused by the scattering of linear waves onto the spacetime curvature generated by the total mass-energy of the source. Quite naturally, the tails of tails are caused by curvature scattering of the tails of waves themselves. The tails of tails are associated with the cubic nonlinear interaction between two mass monopole moments and, dominantly, the mass quadrupole of the source. In this paper we determine the radiation field at large distances from the source for this particular monopole-monopole-quadrupole interaction. We find that the tails of tails appear at the third post-Newtonian (3PN) order beyond the usual quadrupole radiation. Motivated by the need for accurate templates to be used in the data analysis of future detectors of gravitational waves, we compute the contribution of tails, and of tails of tails, up to the 3.5PN order in the energy flux generated by in-spiralling compact binaries.
