Charged anisotropic compact star core-envelope model with polytropic core and linear envelope

Abstract This manuscript is related to the construction of relativistic core-envelope model for spherically symmetric charged anisotropic compact objects. The polytropic equation state considered core, while it linear in case envelope. We present that envelope and Reissner Nordstr $$\ddot{o}$$ o ¨ m exterior regions stars match smoothly. It has been verified all physical parameters are well behaved core region SAX J1808.4-3658 4U1608-52. Various inside star discussed herein, non-singularity continuity at junction catered as well. Impact object together with on mass, radius compactification factor described by graphical representation both envelop regions. stability worked out help Tolman–Oppenheimer–Volkoff equations radial sound speed.
