[P-PS24_1PM1] Origin and evolution of materials in space

Thu. May 1, 2014 2:15 PM - 4:00 PM 415 (4F)

Convener:*Shogo Tachibana(Department of Natural History Scieces, Hokkaido University), Hitoshi Miura(Graduate School of Natural Sciences, Department of Information and Biological Sciences, Nagoya City University), Takafumi Ootsubo(Astronomical Institute, Tohoku Unuversity), Mitsuhiko Honda(Department of Mathematics and Physics, Kanagawa University), Chair:Takafumi Ootsubo(Astronomical Institute, Tohoku Unuversity)

Recent progresses 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 comprehensive understanding of dust and gas in space and their role in evolution of galaxies, stars, and planetary systems. In this session, based on latest results on observations, experiments, planetary missions, and theoretical studies on materials in space, we discuss next steps in science for materials in space.
