Scope
Recent progress in astronomical observations, laboratory experiments, solar system exploration, and theoretical studies has enabled us to understand the origin and evolution of materials (dust and gas) in the Milky Way, protoplanetary disks, and circumstellar environments of late-type giant stars from a material science perspective, leading to the development of fields such as astrochemistry and astromineralogy. To understand the roles that dust and gas play in the evolution of galaxies, stars, and planetary systems, it is increasingly important to link astronomical and astrophysical research with material science studies from chemical and mineralogical perspectives. This session will bring together results from laboratory experiments and analyses of extraterrestrial samples covering diverse environments from high-temperature circumstellar regions to low-temperature molecular clouds, the latest astronomical observations including ALMA and JWST, which continue to produce remarkable results, and discussions anticipating future observations with ground-based large telescopes, such as the TMT project, expected to pioneer frontiers both within and beyond the solar system. In this session, we will discuss from both perspectives what approaches are possible from astronomical observations and material science to understand the evolution and formation of materials in the universe.
