Abstract

In the five-dimensional Kaluza–Klein (KK) theory there is a well known class of static and electromagneticfree KK-equations characterized by a naked singularity behavior, namely the Generalized Schwarzschild solution (GSS). We present here a set of interior solutions of fivedimensional KK-equations. These equations have been numerically integrated to match the GSS in the vacuum. The solutions are candidates to describe the possible interior perfect fluid source of the exterior GSS metric and thus they can be models for stars for static, neutral astrophysical objects in the ordinary (four-dimensional) spacetime. 00A9; Springer-Verlag / Società Italiana di Fisica 2011.
