Scope There are fundamental links between the formation and evolution of planets and their satellites to that of their cores, both in terms of magnetic field generation and chemical and physical structures. Defining properties of cores and core materials are therefore important for understanding their internal structures, evolution, and thermal profile. Recent advances in experimental and theoretical studies provide new insights into the Earth's cores and the cores of other terrestrial bodies. We seek to understand the nature and role of light elements in the early history of planets and better define their current state. Recent, on-going and future space missions have and will continue to obtain data on the internal structure of terrestrial planets (e.g., Mars and Mercury) and planet-satellite systems. We welcome presentations on recent advances on the physical and chemical properties of cores and discussions regarding the latest views of their formation and evolution. We welcome contributions from mineral/rock physics, geophysics, geochemistry, geodynamics, and planetary science. We also welcome papers stimulating an interdisciplinary collaboration relating to establishment of the Study of Earth Deep Interior (SEDI)-Japan community. The Commission of Physics of Minerals of the International Mineralogical Association (CPM-IMA) sponsors this session.
