Title: On the stability of universal extradimensional disks
Author: Coimbra-Araujo, CH
Letelier, PS
Abstract: The oscillation frequencies for perturbed circular geodesics on a universal extradimensional disk are computed. In particular, we investigate a disk constructed from Schwarzschild and Chazy-Curzon solutions with a simple extension for extra dimensions, by solving vacuum Einstein field equations for an extension of the Weyl metric. We find that it is possible to find a range of possible solutions where such a disk is stable and thus we derive the geodesic orbits for this situation.
