On the equations of motion for a charged dust — •Volker Perlick and Anthony Carr — Physics Department, Lancaster University, Lancaster LA1 4YB, UK

We consider the equations of motion for a charged dust coupled to Maxwell's equations on a general-relativistic spacetime (Maxwell-Lorentz equations). These equations of motion provide a mathematical model, e.g., for the electron component of a (cold) plasma in applications to astrophysics, but also for a beam of charged particles in an accelerator. After establishing some general features of the Maxwell-Lorentz equations, spherically symmetric solutions on Minkowski spacetime are discussed in greater detail. Some unexpected and counter-intuitive properties are found.
