摘      要：We establish new charged stellar models from the Einstein-Maxwell field equations for relativistic superdense objects outfitted with three *** core layer is described by a linear equation of state(EoS)describing quark matter,while the intermediate layer is described by a Bose-Einstein condensate EoS for Bose-Einstein condensate matter and the envelope layers satisfying a quadratic EoS for the neutron *** have specified a new choice of the electric field and one of the metric *** is interesting to note that the choice of electric field in this model can be set to vanish and we can regain earlier neutral *** generated depict that the matter variables,gravitational potentials and other physical conditions are consistent with astrophysical *** interior layers and exterior boundary are also matched.
