Abstract
In this work we present some new results obtained in a study of the phase diagram of charged compact boson stars in a theory involving a complex scalar field with a conical potential coupled to a U(1) gauge field and gravity. We here obtain new bifurcation points in this model. We present a detailed discussion of the various regions of the phase diagram with respect to the bifurcation points. The theory is seen to contain rich physics in a particular domain of the phase diagram.

We first consider the phase diagram of the theory based on the values of the fields at the origin of the boson star, the vector field, b(0), and the scalar field, h(0), obtained by studying a sequence of values of the parameter a
In the region IIA, the solutions exhibit the typical oscillating/spiral behavior known for non-compact boson stars
