Sandblasting the $\textit{r}$-Process: Spallation of Ejecta from Neutron Star Mergers

24 Apr 2020 Wang Xilu Fields Brian D. Mumpower Matthew Sprouse Trevor Surman Rebecca Vassh Nicole

Neutron star mergers (NSMs) are rapid neutron capture ($\textit{r}$-process) nucleosynthesis sites that expel matter at high velocities, from $0.1c$ to as high as $0.6c$. Nuclei ejected at these speeds are sufficiently energetic to initiate spallation nuclear reactions with interstellar medium particles... (read more)
