Symposium on Space Weather and Habitable Zones


Just as solar activity has a strong influence on terrestrial life, stellar activities, such as superflares, may have profound impacts on associated planetary systems. Accordingly, the definition of the habitable zone, which has traditionally considered only normal radiation flux from the host star, should perhaps be amended to reflect stellar flares as well, that may expose planets to potentially disruptive high-energy particles.
Kyoto University has developed and launched an integrated database of confirmed extrasolar planets, or “exoplanets”, called ExoKyoto, to facilitate comprehension of distant planetary systems. Each of the host stars in this catalogue is listed with its habitable zones calculated based on observed/estimated parameters. Stellar flares and their potential impacts on planetary systems, estimated based on currently available knowledge and information, are to be incorporated into this database.
This symposium will present state-of-the-art research on these topics.
