Black hole sensitivity in Einstein--aether theory

Abstract

We numerically find the solutions for slowly moving Schwarzschild black holes in Einstein--aether theory. We use these solutions to compute the sensitivity parameter which describes the coupling of the black hole to the aether field within point-particle effective theory. A simple analytic approximation for the dependence of the sensitivity on the Einstein--aether parameters is derived.
