Abstract
The present work is concerned with the asymptotic properties of the field radiated by a classical spinning (and nonspinning) point charge in arbitrary motion. It is demonstrated that the expression found for the radiated angular momentum is satisfactory in that it is a 4-tensor which is spacelike surface-independent. The angular-momentum radiation rate is then expressed in terms of the retarded kinematic properties of the particle. In addition, a ``center-of-energy'' theorem is proved for nonspinning charges in arbitrary motion—a result which follows from the demonstrated result that nonspinning charges also radiate angular momentum. Finally, it is demonstrated that the (linear) energy-momentum radiation rate is independent of the spin of the involved charge. The discussion is manifestly covariant throughout and many mathematical details are deferred to appendices.
