Relativistic objects - Opis:
- In this paper, we studied the behavior of relativistic objects with anisotropic charged matter distribution considering a prescribed form for the gravitational potential Z(x) which depends on an adjustable parameter n. The equation of state presents a quadratic relation between the energy density and the radial pressure. New exact solutions of the Einstein-Maxwell system are generated. A physical analysis of electromagnetic field indicates that is regular in the origin and well behaved. We show as a variation of the adjustable parameter n causes a modification in the charge density, the radial pressure and the mass of the stellar object.
