Abstract The simulation of heavy element nucleosynthesis requires input from yet-to-be-measured nuclear properties. uncertainty in the values these off-stability properties propagates to uncertainties predictions elemental and isotopic abundances. However, for any given astrophysical explosion, there are many different trajectories, i.e., temperature density histories, experienced by outflowing material, thus can come into play. We consider combined results 460,000 trajectories a black hole accretion disk find spread due solely unknown be factor few. analyze this relative model variations conclude that attributed combination region abundance pattern. calculate cross-correlation between mass changes show how among participating nuclei may explored. Our provide further impetus measurements multiple quantities on individual short-lived neutron-rich isotopes at modern experimental facilities.
