Nonlinear gravitational self-force: second-order equation of motion
When a small, uncharged, compact object is immersed in an external background spacetime, at zeroth order in its mass it moves as a test particle in the background. At linear order, its own gravitational field alters the geometry around it, and it moves instead as a test particle in a certain effective metric satisfying the linearized vacuum Einstein equation. In the letter [Phys. Rev. Lett. 109...
متن کاملPerspective on gravitational self-force analyses
A point particle of mass μ moving on a geodesic creates a perturbation hab, of the spacetime metric gab, that diverges at the particle. Simple expressions are given for the singular μ/r part of hab and its tidal distortion caused by the spacetime. This singular part hab is described in different coordinate systems and in different gauges. Subtracting hab from hab leaves a regular remainder hab....

A point particle of mass μ moving on a geodesic creates a perturbation hab, of the spacetime metric gab, that diverges at the particle. Simple expressions are given for the singular μ/r part of hab and its distortion caused by the spacetime. This singular part hS ab is described in different coordinate systems and in different gauges. Subtracting hS ab from hab leaves a regular remainder h R ab...
متن کاملGravitational self force and gauge transformations
We explore how the gravitational self force (or “radiation reaction” force), acting on a pointlike test particle in curved spacetime, is modified in a gauge transformation. We derive the general transformation law, describing the change in the self force in terms of the infinitesimal displacement vector associated with the gauge transformation. Based on this transformation law, we extend the re...
متن کاملGravitational self-force by mode sum regularization
We propose a practical scheme for calculating the local gravitational self-force experienced by a test mass particle moving in a black hole spacetime. The method—equally effective for either weak or strong field orbits—employs the mode-sum regularization scheme previously developed for a scalar toy model. The starting point for the calculation, in this approach, is the formal expression for the...
