The study of extended test bodies in curved spacetime can capture important aspects of the two-body problem in general relativity. Significant strides in this program are taken in this paper. The results have wide applicability but are particularly well suited for the computation of waveforms relevant for gravitational wave detection, which is currently undergoing an exciting period of experimental discovery.
