摘　　要：The three-body force ( TBF ) effect on the proton fraction in the β-stable neutron star matter has been investigated within the iso-spin dependent Brueckner Hartree-Fock ( BHF ) framework, by adopting the microscopic TBF based on a meson-exchange current model of interaction mediated by the excitation of NN couples and low-lying nucleon resonances The calculated proton fraction vs. baryon density is displayed
