Can Neutron Star Mergers Alone Explain the r-process Enrichment of the Milky Way?

Can Neutron Star Mergers Alone Explain the r-process Enrichment of the Milky Way?

Comparing Galactic chemical evolution models to the observed elemental abundances in the Milky Way, we show that neutron star mergers can be a leading r-process site only if at low metallicities such mergers have very short delay times and significant ejecta masses that are facilitated by the masses...
