The Search for Extra-terrestrial Mother Planets Catalogue (SEMPAC) will be used to search for potentially habitable mother planets and to derive data on stellar activity about their host stars. We have conducted observation for the stellar activities for the planetary hosting stars in order to identify critical ionizing radiation for the planetary environment using Seimei Telescope. This activity may provide useful information for the dose of ionizing radiation and the estimation of atmospheric escape to secure planetary surface environment whether planets may preserve the aquatic environment. For the initiation of our observation, we observed the GJ180, GJ273, GJ357, GJ3293, GJ3323, Ross-128, and Kepler-1544. In additionwe also observed active young sun’s analogues as Kappa1 Ceti and V993 Tau.

In this presentation we’ll introduce the preliminary outcome throughout the observation activities via Seimeitelescope and input into SEMPAC, by focusing on their potential impact in their atmospheric environment of the host star.
