|Gravitational waves contain tail effects that are due to the backscattering
of linear waves in the curved space-time geometry around the source. The
knowledge as well as the accuracy of the two-body inspiraling post-Newtonian
(PN) dynamics and of the gravitational-wave signal has been recently
improved, notably by computing the spin-orbit (SO) terms induced by tail
effects in the gravitational-wave energy flux at the 3PN order. Here we sketch
this derivation, which yields the phasing formula including SO tail effects
through the same 3PN order. Those results can be employed to improve the
accuracy of analytical templates aimed at describing the whole process of
inspiral, merger, and ringdown.
