Impact of nuclear masses on r-process nucleosynthesis: bulk properties versus shell effects
Samuel A. Giuliani, Gabriel Martínez-Pinedo, Andreas Bauswein +1
We investigate the impact of the model estimating the masses of exotic nuclei on r-process nucleosynthesis, assessing the dependence of the abundance distribution on the specific p…

Actinide signatures in low electron fraction kilonova ejecta
Quentin Pognan, Meng-Ru Wu, Gabriel Martínez-Pinedo +4
Neutron star (NS) mergers are known to produce heavy elements through rapid neutron capture (r-process) nucleosynthesis. Actinides are expected to be created solely by the r-proces…

Competition between allowed and first-forbidden decay in -process waiting-point nuclei within a relativistic beyond-mean-field approach
Caroline E. P. Robin, Gabriel Martínez-Pinedo
We compute -decay half-lives of isotonic nuclear chains located at neutron shell closures , , and , which are of particular importance for the -process n…
