A RADIATING DYON SOLUTION

We give a non-static exact solution of the Einstein-Maxwell equations (with null fluid), which is a non-static magnetic charge generalizatio n to the Bonnor-Vaidya solution and describes the gravitational and el ectromagnetic fields of a non-rotating massive radiating dyon. In addi tion, using the energy-momentum pseudotensors of Einstein and Landau a nd Lifshitz we obtain the energy, momentum, and power output of the ra diating dyon and find that both prescriptions give the same result.
