Generating physically realizable stellar structures via embedding
In this work we present an exact solution of the Einstein-Maxwell field
equations describing compact, charged objects within the framework of classical
general relativity. Our model is constructed by embedding a four-dimensional
spherically symmetric static metric into a five dimensional flat metric. The
source term for the matter field is composed of a perfect fluid distribution
with charge. We show that our model obeys all the physical requirements and
stability conditions necessary for a realistic stellar model. Our theoretical
model approximates observations of neutron stars and pulsars to a very good
degree of accuracy.Comment: 14 figure
