[P-CG27] Origin and evolution of materials in space

convener:Hideko Nomura(Division of Science, National Astronomical Observatory of Japan), Takafumi Ootsubo(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Hitoshi Miura(Graduate School of Natural Sciences, Department of Information and Basic Science, Nagoya City University), Aki Takigawa(Department of Earth and Planetary Science, The University of Tokyo)

Recent progress of astronomical observations, laboratory experiments, solar-system exploration, and theoretical work have enabled us to attempt to understand the origin and evolution of materials (dust and gas) in space in the context of material science. It is thus important to link further planetary material science and astronomy for a comprehensive understanding of dust and gas in space and their role in the evolution of galaxies, stars, and planetary systems. Infrared observations with future large satellites/telescopes, such as SPICA and TMT, are suitable for the study of gas and dust, and are expected to bring a new frontier of gas/dust study. In this session, based on the latest results on astronomical observations (ALMA, etc.), experiments, and theoretical studies on materials in space, we discuss the next steps in science for materials in space to maximize the outcome of the observations with the future satellites/telescopes.
