Abstract

New exact solutions of Einstein’s field equations for charged stellar models by assuming linear equation of state \(P_{r}=A(\rho -\rho _{a}) \), where \(P_{r} \) is the radial pressure and \(\rho _{a} \) is the surface density. By assuming \(e^{\lambda } = 1+\frac{r^{2}}{R^{2}} \) for metric potential. The physical acceptability conditions of the model are investigated, and the model is compatible with several compact star candidates like 4U 1820-30, PSR J1903+327, EXO 1785-248, LMC X-4, SMC X-4, Cen X-3. A noteworthy feature of the model is that it satisfies all the conditions needed for a physically acceptable model.
