Phys. Rev. C 62, 035801 (2000) [8 pages]Hyperon-hyperon interactions and properties of neutron star matterReceived 11 April 2000; published 27 July 2000 We present results from Brueckner-Hartree-Fock calculations for β-stable neutron star matter with nucleonic and hyperonic degrees of freedom, employing the most recent parametrizations of the baryon-baryon interaction of the Nijmegen group. It is found that the only strange baryons emerging in β-stable matter up to total baryonic densities of 1.2 fm-3 are Σ- and Λ. The corresponding equations of state are then used to compute properties of neutron stars such as masses and radii. © 2000 The American Physical Society URL:
