Mergers of compact object binaries involving neutron stars are responsible for electromagnetic radiation as well as gravitational waves. Hydrodynamic interaction during the merger drives ejection of a substantial amount of neutron-rich material. The ejecta is expected to accompany various electromagnetic radiation or electromagnetic counterparts such as a kilonova/macronova, which was claimed to be detected in recent followup observations of GRB 130603B. In this talk, we present recent results obtained via merger simulations of binary neutron stars and black hole-neutron star binaries, and also show results of radiation transfer simulations for kilonova/macronova performed incorporating ejecta properties inherited from merger simulations.
