[P-EM16] Heliosphere and Interplanetary Space

Mon. May 26, 2025 3:30 PM - 5:00 PM 302 (International Conference Hall, Makuhari Messe)

convener:Kazumasa Iwai(Institute for Space–Earth Environmental Research (ISEE), Nagoya University), Yasuhiro Nariyuki(Faculty of Education, University of Toyama), Masaki N Nishino(Japan Aerospace Exploration Agency, Institute of Space and Astronautical Science), Ken Tsubouchi(University of Electro-Communications), Chairperson:Kazumasa Iwai(Institute for Space–Earth Environmental Research (ISEE), Nagoya University), Masayoshi Kozai(Polar Environment Data Science Center, Joint Support-Center for Data Science Research, Research Organization of Information and Systems)

This session aims to share new findings on the heliosphere and interplanetary space. Presentations of recent studies from any approach (integrated observation/theoretical modeling/massive numerical simulation/development of instrumentation) are welcome. The topic of this session contains a wide range of phenomena and regions: solar corona/solar flares/Coronal mass ejections (CMEs)/solar wind/high-energy particles, and their impact on the terrestrial/planetary/lunar environments, solar activity, global structure of the heliosphere, cosmic rays, and outer heliosphere. Fundamental physics problems related to shocks/waves/turbulence/particle transport and acceleration are also included as the main targets of this session.
