Query: Gravitating Stationary Dyons and Rotating Vortex Rings   We construct dyons, and electrically charged monopole-antimonopole pairs and
vortex rings in Yang-Mills-Higgs theory coupled to Einstein gravity. The
solutions are stationary, axially symmetric and asymptotically flat. The dyons
with magnetic charge $n\ge 2$ represent non-static solutions with vanishing
angular momentum. The electrically charged monopole-antimonopole pairs and
vortex rings, in contrast, possess vanishing magnetic charge, but finite
angular momentum, equaling $n$ times their electric charge.
