Origin and evolution of solid materials in stars and planets
Scope
Recent progresses of astronomical observations, laboratory experiments, and theoretical work have enabled us to study the evolution of solid materials in our Solar System as a part of a general star and planetary system formation and evolution study. Collecting these new scientific results, in this session, further progresses of our science are pursued.
