More than 5,700 exoplanets have been discovered so far by various astronomical instruments to search for exoplanets. Our group has also developed an infrared Doppler instrument to search for M dwarf exoplanets. This instrument was installed on the Subaru Telescope and is being operated for six years starting in 2019 within the framework of the IRD-Subaru Strategic Plan. In this paper, we present the near-infrared optical frequency comb instrument for astronomy, which is guaranteeing the precision of observations in the project.
