Title: Newtonian And General Relativistic Models Of Spherical Shells
Author: Vogt D.
Letelier P.S.
Abstract: A family of spherical shells with varying thickness is derived by using a simple Newtonian potential-density pair. Then, a particular isotropic form of a metric in spherical coordinates is used to construct a General Relativistic version of the Newtonian family of shells. The matter of these relativistic shells presents equal azimuthal and polar pressures, while the radial pressure is a constant times the tangential pressure. We also make a first study of stability of both the Newtonian and relativistic families of shells. © 2009 The Authors. Journal compilation © 2009 RAS.
