On the Magnetosphere of an Accelerated Pulsar
T. Daniel Brennan, Samuel E. Gralla
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. N…
Exact Solutions to Force-Free Electrodynamics in Black Hole Backgrounds
T. Daniel Brennan, Samuel E. Gralla, Ted Jacobson
A shared property of several of the known exact solutions to the equations of force-free electrodynamics is that their charge-current four-vector is \textit{null}. We examine the g…
Hidden Momentum and Black Hole Kicks
Samuel E. Gralla, Frank Herrmann
A stationary magnetic dipole immersed in an electric field carries "hidden" mechanical momentum. However, the fate of this momentum if the fields are turned off is unclear. We cons…
Mass, Charge and Motion in Covariant Gravity Theories
Samuel E Gralla
Previous work established a universal form for the equation of motion of small bodies in theories of a metric and other tensor fields that have second-order field equations followi…
