The r-process in supernovae with new microscopic mass formulae Original Research Article

We examine the effects of the newly-derived microscopic Hartree-Fock-Bogoliubov (HFB) mass formulae on the r-process nucleosynthesis and analyse to what extent a solar-like r-abundance distribution can be obtained. The r-process calculations with the HFB-2 mass formula are performed, adopting the parametrized model of the prompt explosion from a collapsing O-Ne-Mg core for the physical conditions. The result is compared with those obtained with the HFB-7 and droplet-type mass formulae.
