Abstract:
We investigate how a spherically symmetric scalar field can modify the
Schwarzschild vacuum solution when there is no exchange of energy-
momentum between the scalar field and the central source of the
Schwarzschild metric. This system is described by means of the
gravitational decoupling by Minimal Geometric Deformation (MGD-
decoupling), which allows us to show that, under the MGD paradigm, the
Schwarzschild solution is modified in such a way that a naked
singularity appears.
