Abstract

In this work, we have studied the effect of three-nucleon interaction on the neutron stars structure. In our calculations, we have considered the neutron star matter as a beta-stable nuclear matter. We have put the results concerning the TBF effect in perspective against two-body results and other calculations of three-nucleon interactions, using the Urbana v14 potential and the parabolic approximation of the nuclear-matter energy for approximating the problem of asymmetric nuclear matter. As such, solving the Tolman-Oppenheimer-Volkoff equation, we have estimated bulk properties of neutron stars and investigated how the present calculations would agree with the expected dynamical-stability condition.
