Description
We study the dynamics of electrically charged black-hole binaries and their gravitational-wave emission during the inspiral phase. Within the post-Newtonian framework, we derive the conservative and dissipative dynamics up to second order (2PN). We compute the NNLO conservative Lagrangian, LO dissipative effects in harmonic and Lorenz gauges, and provide the equations of motion, center-of-mass transformations, and the
Lagrangian/Hamiltonian in ADM-type coordinates. We also obtain the total energy flux of the system at 2PN accuracy. Specifically, we study both the usual tensor contribution and the new vector contribution associated with the presence of the electromagnetic field.
