This is the quasi-Newtonian approximation, where you are using a relativistic theory but basically neglecting everything $\mathcal{O}(v/c)$, which implies that the source is moving according to Newton's laws. In the post-Newtonian expansion, you start considering the first order terms in $v/c$(squared), which is appropriate for describing also the motion of the source, especially in a binary system. An excellent reference is the Living review by Luc Blanchet. | |
