Abstract

The mechanism of the appearance of neutron complexes, which at the final stage of their development, evolve into neutron stars, is described. It is shown that for a quantitative description it is necessary to use a generalization of the Newton-Schrödinger equations taking into account the next terms in the decomposition of explicit Dirac – Maxwell equations on c^-2. In this approximation, the problem is described by the well-known Gross-Pitaevskii equation, the numerical analysis of which is performed for the spherically symmetric case. The result depends on the value of the parameter α equal to the ratio of the gravitational radius of the neutron complex to twice the Compton wavelength. For small values of α <0.5, the solutions describe a neutron star; for α > 0.5, the description corresponds to its gravitational collapse. This is consistent with the analysis of the general 3-dimensional case.
