    A neutral stellar model with quadratic equation of state
    (Springer, 2022) Sunzu, Jefta M.; Mathias, Amos V
    We generate a new exact model for neutral anisotropic star using Einstein field equations. In this model, we consider a quadratic equation of state (QEoS) and a choice of gravitational potential which generalizes the choice formulated by Pant and Fuloria. We generate stellar masses consistent with previous findings which describe the astrophysical objects like PSR J1614-2230, Cen X-3, Vela X-1 and Exo 1785-248. New relativistic stellar masses and surface gravitational redshifts in acceptable ranges are also generated using our model. It is observed that the matter variables and gravitational potentials are well behaved. The model satisfies energy and stability conditions and all forces within the stellar object sum to zero.
