Symposium on Space Weather and Habitable Zones – June 27th & 28th Kyoto

Symposium on Space Weather and Habitable Zones – June 27th & 28th Kyoto

Stellar activities including stellar superflares may have severe impacts on associated planetary systems. Likewise, solar activity has a strong influence on terrestrial activities. In addition to the traditional habitable zones based on the normal radiation flux from the host star, new habitable zone definitions should incorporate stellar flare activities, which may disturb planets located in the habitable zone through high energy particles.

An integrated database of confirmed exoplanets has been developed and launched as “ExoKyoto,” for the purpose of better comprehension of exoplanetary systems in different star systems. Each hoststar can be referred to in the catalogue with its habitable zone calculated, based on the observed/estimated star parameters. Stellar flare and its impacts on planetary systems are to be included in ExoKyoto and launched reflecting current available knowledge and information.

This symposium aims to identify state-of-art research outcomes on these topics.
