Neutron-capture uncertainties limit r-process residuals
What the study found Some r-process, or rapid neutron-capture, isotope residuals in the solar system remain significantly uncertain because uncertainties in s-process, or slow neutron-capture, abundances propagate into them. Why the authors say this matters The authors say this is important because r-process residuals are used as a benchmark in stellar models of explosive nucleosynthesis,…
