A three-dimensional hydrodynamical line profile analysis of iron lines and barium isotopes in HD140283
Gallagher, A. J.; Ludwig, H. G.; Ryan, Sean G.; Aoki, W. (2015-07-31)Heavy-elements, i.e. those beyond the iron peak, mostly form via two neutron capture processes: the s- and r-process. Metal-poor stars should contain fewer isotopes that form via the s-process, according to currently ...
