Talk	Oral abstract	Title	Tail-induced spin-orbit effect in the gravitational radiation of compact binaries
Co-authors	Luc Blanchet, Alessandra Buonanno
Abstract	Gravitational waves contain tail effects which 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) evolution and gravitational-wave signal are improved by computing the spin-orbit terms induced by tail effects. Notably, their contribution at 3PN order to the gravitational-wave energy flux, and at 2.5PN and 3PN orders to the wave polarizations is derived by solving the precessing dynamics at the relevant order. This is then used to obtain the spin-orbit tail effects in the phasing through 3PN order. Those results can be employed to carry out more accurate comparisons with numerical-relativity simulations and to improve the accuracy of analytical templates aimed at describing the whole process of inspiral, merger, and ringdown.
