Gamma-ray Diagnostics of r-process Nucleosynthesis in the Remnants of Galactic Binary Neutron-Star Mergers

We perform a full nuclear-network numerical calculation of the \(r\)-process nuclei in binary neutron-star mergers (NSMs), with the aim of estimating \(\gamma\)-ray emissions from the remnants of Galactic NSMs up to \(10^6\) years old. The nucleosynthesis calculation of 4,070 nuclei is adopted to pr...
