Descripción
Dynamical problems associated with the orbital motion of dust particles
in strong gravitational and radiation fields are analyzed. The general
relativistic equations for the motion of a single dust particle are
derived, and the static, spherically symmetric situation described by
the Schwarzschild metric is considered. Two sharply differentiated
regions are tentatively discerned in relativistic dust rings. In the
outer regions, dust particles evolve according to a derived expression,
reemitting preferentially in a cone centered in the plane of motion,
while in the inner ring the particles fall approaching radial geodesics
near the speed of light.
