Abstract:We use up-to-date constraints on the mass and radius of 15 neutron star objects and pulsars, from electromagnetic and gravitational wave observables and different theoretical schemes, to extend the nuclear equation of state (EOS) based on realistic M3Y nucleon-nucleon interaction, which truly accounts for the low-density EOS of nuclear matter, to describe dense nuclear matter. The considered EOSs are employed to map the mass-radius profiles using the Tolman-Oppenheimer-Volkoff equations of hydrostatic equilibr… Show more
