Abstract:
We investigate how a spherically symmetric fluid modifies the
Schwarzschild vacuum solution when there is no exchange of energy-
momentum between the fluid and the central source of the Schwarzschild
metric. This system is described by means of the gravitational
decoupling realised via the minimal geometric deformation approach,
which allows us to prove that the fluid must be anisotropic. Several
cases are then explicitly shown.
