Revisiting Planetary Systems in Okayama Planet Search Program
Abstract In this study, we revisit 32 planetary systems around evolved stars observed within the framework of the Okayama Planet Search Program (OPSP) and its collaborative framework of the East Asian Planet Search Network (EAPS-Net) to search for additional companions and investigate the properties of stars and giant planets in multiple-planet systems.
