摘要：

Assuming that the physical three-space in a relativistic superdense star has the geometry of a three-spheroid, a static spherically symmetric model based on an analytic closed-form solution of Einstein's field equations is presented. Assuming the density of the order of 2×1014 g cm-3, estimates of the total mass and size of the stars of the model are obtained for various values of a density-variation parameter that is suitably defined. The total mass and the boundary radius of each of these models are of the order of the mass and size of a neutron star. © 1990 American Institute of Physics.
