Merger and mass ejection of neutron-star binaries in numerical relativity

On August 17th, 2017, merger of binary neutron stars was observed for the first time by gravitational-wave and electromagnetic telescopes. Optical and infrared observations in particular agree broadly with the prediction by numerical relativity. From this April, advanced LIGO and VIRGO are in O3 observation and already had a few candidates of neutron-star mergers. We expect several more observations of neutron-star mergers (including black hole-neutron star merger). I will review our current understanding for neutron-star mergers and related mass ejection that are obtained by numerical relativity simulations and summarize predicted observational (optical and infrared) features.
