摘要
Exact solutions to the Einstein field equations for class I spacetime symmetry in relativistic stars are generated.The symmetry provides a relation between the gravitational potentials that lead to generalized solutions of the Einstein field equations.We choose one of the gravitational potentials on a physical basis,which allows us to obtain the other gravitational potential via an embedding approach.It is therefore possible to generate a model with astrophysical significance.The model generated satisfies physical properties like stability,causality,regularity,equilibrium and energy conditions.
