 Chandrasekhar–Page equations

The Chandrasekhar-Page equations describe the structure of a neutron star, specifically its equilibrium under the influence of gravity and the pressure of its degenerate matter. They are derived from the principles of general relativity and account for the balance between the gravitational forces trying to compress the star and the pressure exerted by the neutron fluid. The equations involve several critical parameters, including the mass, radius, and internal energy density of the star.
