The nucleosynthesis of Ba in the Early Universe. Constraints from elemental abundances and isotopic ratios

Riano E. Giribaldi, Marco Palla, Laura Magrini +6

The [Ba/Eu] abundance ratio is commonly adopted as a tracer of the relative contributions of the slow (s) and rapid (r) neutron-capture processes. However, at [Fe/H] < -2 dex, Ba c…
