    "abstract": "In this paper the impact of the strength of hyperon-nucleon and\nhyperon-hyperon on the maximum neutron star mass is shown. The strong\nhyperon-hyperon coupling constant together with the additional nonlinear meson\ninteraction terms lead to the essential softening of the equation of state and\nto the existence of another more compact branch of stable neutron star\nconfigurations. The analysis of the mass-radius relations leads to the\nconclusion that the additional stable configurations of hyperon-rich neutron\nstars are characterized by the reduced value of radii.",
