Yes, mostly, but it takes the form of significant gravitational wave emission only when the bodies are very close together. (Much less than an AU, I think, although don't quote me on that.) For larger distances, it's mostly a matter of ejecting dust and other matter in the vacinity. https://en.wikipedia.org/wiki/Dynamical_friction https://en.wikipedia.org/wiki/Dynamical_friction
