Abstract

In a SO(3,1)×U(1) framework, we analytically derive the first-order approximating solutions to the system of Klein–Gordon–Maxwell–Einstein equations describing a minimally coupled charged boson field to a spherically symmetric spacetime. Within a perturbative approach, we analyze the feedback of gravity and electric field on the charged scalar source and we get the coherent source-field regeneration rate. It turns out that we are dealing with an extremely short time-constant which is confirming the other authors' conclusion that intense gravitational bursts are accompanying the boson star formation.
