# Magnetosphere of an Accelerated Pulsar

@article{Brennan2013MagnetosphereOA, title={Magnetosphere of an Accelerated Pulsar}, author={Theodore D. Brennan and Samuel E. Gralla}, journal={arXiv: High Energy Astrophysical Phenomena}, year={2013} }

We report on a remarkable class of exact solutions to force-free electrodynamics that has four-current along the light cones of an arbitrary timelike worldline in flat spacetime. No symmetry is assumed, and the solutions are given in terms of a free function of three variables. The field configuration should describe the outer magnetosphere of a pulsar moving on the worldline. The power radiated is the sum of an acceleration (Larmor-type) term and a pulsar-type term.
