Description
I will discuss what is the current state of the art for gravitational self-force waveforms and the ingredients that go into them. I will discuss how the second-order metric perturbation is used to calculate the amplitude, flux and phase of a gravitational wave and how the slowly-evolving first-order metric perturbation contributes to sourcing perturbations at second order. I will demonstrate the validity of the model as compared to numerical relativity simulations and effective-one-body theory, noting the interesting result that the small-mass ratio approximation remains valid for near-comparable mass ratio binaries in the non-spinning case for quasicircular orbits.
