Frozen Bardeen-Dirac stars and light ball

Abstract In this paper, we study solutions of a static spherically symmetric system, which is composed of the coupling with the Bardeen action and two Dirac fields. For the case where only the Bardeen action is present, the magnetic charge q can be infinite, then when the magnetic charge is greater...
