Einstein--Proca model: spherically symmetric solutions

Abstract

The Proca wave equation describes a classical massive spin 1 particle. We analyze the gravitational interaction of this vector field. In particular, the spherically symmetric solutions of the Einstein-Proca coupled system are obtained numerically. Although at infinity the metric field approaches the usual Schwarzschild (Reissner-Nordstr\"om) limit, we demonstrate the absence of black hole type configurations.
