In this work, we use the gravitational decoupling framework through the extended minimal geometric deformation to construct and study a new interior isotropic extension of Einstein’s universe solution. The resulting model fulfills the fundamental physical acceptance conditions. As well, we study the energy exchange between the Einstein’s fluid distribution and an extra perfect fluid which supports the resulting isotropic stellar configuration.
