Murphy, Gabriele Cescutti, Nobuya Nishimura, Raphael Hirschi, Thomas Rauscher","submitted_at":"2017-01-02T19:00:00Z","abstract_excerpt":"The $s$-process in massive stars produces the weak component of the $s$-process (nuclei up to $A \\sim 90$), in amounts that match solar abundances. For heavier isotopes, such as barium, production through neutron capture is significantly enhanced in very metal-poor stars with fast rotation. However, detailed theoretical predictions for the resulting final $s$-process abundances have important uncertainties caused both by the underlying uncertainties in the nuclear physics (principally neutron capture reaction and $\\beta$-decay rates) as well as by the stellar evolution modeling.
