Title: Geodesics around Weyl-Bach's ring solution
Author: D'Afonseca, LA
Letelier, PS
Oliveira, SR
Abstract: We explore some of the gravitational features of a uniform infinitesimal ring both in the Newtonian potential theory and in general relativity. We use a spacetime associated with a Weyl static solution of the vacuum Einstein's equations with ring-like singularity. The Newtonian motion for a test particle in the gravitational field of the ring is studied and compared with the corresponding geodesic motion in the given spacetime. We have found a relativistic peculiar attraction: free-failing particle geodesics lead to the inner rim but never hit the ring.
