The impact of turbulent mixing on the galactic r-process enrichment by binary neutron star mergers

ABSTRACT We study the enrichment of interstellar medium (ISM) with rapid neutron capture (r-process) elements produced in binary star (BNS) mergers. use a semi-analytic model to describe galactic evolution, merger rates and time delay distributions BNS mergers consistent latest population synthesis models. In order dispersion relative abundances r-process iron, we applied turbulent mixing scheme, where freshly synthesized are gradually dispersed ISM. show that within our observed Milky Way stars, particular scatter at low metallicities, can be entirely explained by Our results suggest could dominant source Galaxy.
