Gravitational radiation from compact binary systems in Einstein-Maxwell-dilaton theories

We derive the energy fluxes radiated by compact binary systems, including “hairy” black holes, in Einstein-Maxwell-dilaton theories, for circular orbits and at quadrupolar order. This enables to include in their resummed effective-one-body (EOB) dynamics the effect of the radiation reaction force at the origin of their inspiral and merger. We also exhibit typical examples of the resulting tensor and scalar waveforms.
