Abstract: | On the basis of the general theory of relativity, and within the framework of the model in which the neutron star has a constant density, we investigate the influence of a solid layer of superdense material inside a neutron star on its limiting mass. We show that the existence of such an internal solid shell leads to an increase of the limiting mass of a neutron star in comparison with the case of purely liquid neutron-star matter. This increase of mass can reach 30%.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 2, pp. 46–49, February, 1986. |
