A binary neutron star merger produces gravitational-waves and also electromagnetic transients in multi-wavelenghts. First part of the talk, I will focus on the current status of gravitational waveform modeling for binary neutron star mergers. Using a numerical relativity simulation, we obtain long-term waveforms for several different neutron star equations of state and construct hybrid waveforms with those computed with the effective one body formalism. I will discuss a role of the hybrid waveforms in advanced LIGO observations. Second part of the talk is about electromagnetic signatures after merger. I will show the implication of recent discovery of macronova (also called kilonova) candidates associated with short gamma-ray bursts on the origin of r-process elements and the electromagnetic counterparts of GWs. I will also show the expected radio counterparts and the advantages of the radio follow-up observations of GWs.
