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

We generalize the bumpy black hole framework to allow for alternative theory deformations. We construct two model-independent parametric deviations from the Kerr metric: one built from aExpand

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
Studies of strong-field gravity : testing the black hole hypothesis and investigating spin-curvature coupling
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
Gravitational self-force in nonvacuum spacetimes: An effective field theory derivation
In this paper we investigate the motion of small compact objects in non-vacuum spacetimes using methods from effective field theory in curved spacetime. Although a vacuum formulation is sufficient inExpand
Modified Gravity Corrections in Fundamental Orbital Frequencies in Kerr Spacetime

Effective gravitational wave stress-energy tensor in alternative theories of gravity
The inspiral of binary systems in vacuum is controlled by the stress-energy of gravitational radiation and any other propagating degrees of freedom. For gravitational waves, the dominant contributionExpand

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
Equations of motion in general relativity of a small charged black hole
We present the details of a model in general relativity of a small charged black hole moving in an external gravitational and electromagnetic field. The importance of our model lies in the fact thatExpand
A rigorous derivation of gravitational self-force
There is general agreement that the MiSaTaQuWa equations should describe the motion of a 'small body' in general relativity, taking into account the leading order self-force effects. However,Expand
