Gravity in binary systems at the fifth and sixth postNewtonian order
Abstract
Binary sources of gravitational waves in the early inspiral phase are accurately described by a postNewtonian expansion in small velocity and weak interaction. We compute the conservative dynamics to fifth and partial sixth order using a nonrelativistic effective field theory. We give predictions for central observables and determine the required coefficients for the construction of an Effective OneBody Hamiltonian, extending the applicability of our results to the late inspiral and merger phases.
