We formulate the set of self-consistent ground-state equilibrium equations for neutron star cores taking into account quantum statistics, electro-weak, and strong interactions, within the framework of general relativity. The strong interaction between nucleons is modeled through the sigmaomega-rho meson exchange in the context of the extended Walecka model, all duly expressed in general relativity. We found the generalization to the works of Klein (1949), of Kodama and Yamada (1972) , and of

The consequences of these new conditions of equilibrium on the structure of neutron stars are discussed.
