Gravitational waves from the binary black hole merger GW150914 were detected in 2015. In addition, gravitational waves from the binary neutron star merger GW170817 were detected in 2017, followed by electromagnetic observations at various wavelengths from gamma-ray to radio wavelengths. These observations opened a new era of multi-messenger astronomy and astrophysics. Due to the short distance to the source, the tidal deformability of neutron stars, which contains information on their inner structure, has been estimated for GW170817. In this work, we discuss the possibilities of using gravitational waves to measure the tidal deformability of neutron stars.
