Abstract

We provide a new class of exact solutions for the interior in -dimensional spacetime. The solutions obtained for the perfect fluid model both with and without cosmological constant () are found to be regular and singularity free. It assumes very simple analytical forms that help us to study the various physical properties of the configuration. Solutions without are found to be physically acceptable.
