Sixth post-Newtonian nonlocal-in-time dynamics of binary systems
Sixth post-Newtonian nonlocal-in-time dynamics of binary systems
We complete our previous derivation, at the sixth post-Newtonian (6PN) accuracy, of the local-in-time dynamics of a gravitationally interacting two-body system by giving two gauge-invariant characterizations of its complementary nonlocal-in-time dynamics. On the one hand, we compute the nonlocal part of the scattering angle for hyberboliclike motions; and, on the …
