Abstract:
We employ the minimal geometric deformation approach to gravitational
decoupling (MGD-decoupling) in order to build an exact anisotropic
version of the Schwarzschild interior solution in a space-time with
cosmological constant. Contrary to the well-known Schwarzschild
interior, the matter density in the new solution is not uniform and
possesses subluminal sound speed. It therefore satisfies all standard
physical requirements for a candidate astrophysical object.
