I show how prior work with R. Wald on geodesic motion in general relativity can be generalized to classical field theories of a metric and other tensor fields on four-dimensional spacetime that (1) are second-order and (2) follow from a diffeomorphism-covariant Lagrangian. The approach is to consider a one-parameter-family of solutions to the field equations satisfying certain assumptions designed to reflect the existence of a body whose size, mass, and various charges are simultaneously scaled… Expand
Gravitational self-force in scalar-tensor gravity
Motivated by the discovery of floating orbits and the potential to provide extra constraints on alternative theories, in this paper we derive the self-force equation for a small compact object movingExpand
Dependence of self-force on central object
For a particle in orbit about a static spherically symmetric body, we study the change in self-force that results when the central body type (i.e., the choice of interior metric for the SchwarzschildExpand

Gravitational self-force in nonvacuum spacetimes
The gravitational self-force has thus far been formulated in background spacetimes for which the metric is a solution to the Einstein field equations in vacuum. While this formulation is sufficientExpand

Observations of gravitational systems agree well with the predictions of general relativity (GR); however, to date we have only tested gravity in the weak-field limit. In the next few years,Expand

TLDR
This paper derives the largest corrections to the geodesic law of motion and Fermi-Walker law of transport, due to coupling of the body’s angular momentum and quadrupole moment to the Riemann curvature of the surrounding spacetime. Expand
