Description

We present our latest study of r-process based on a first-principle model of neutron star mergers, in which general relativity, neutrino transport, and magnetic field are self-consistently implemented. We find that magnetic field plays a pivotal role in the mass ejection and the determination of neutron richness. In this presentation, we discuss how neutron star mergers produce the solar-like r-process pattern as well as the actinide boost, which is observed in metal-poor stars. We also compare our result to that for black hole-neutron star mergers with the same model setup.
