Successive planetary exploration/observation missions have provided data on Jovian and Neptunian planets and exoplanets, in addition to the Moon and terrestrial planets. These data include not only the atmospheres and surface environments of these bodies but also a substantial amount of information about their interiors. Prime examples concerning planetary interiors are the density distributions that constrain the layers of planets and magnetic field records that indicate the presence of conductive fluids, which are essential elements for building physical and chemical models of the interior of celestial bodies. To understand the interior regions that account for most of the mass of planetary bodies, combining constraints from these observations with physical properties from mineralogical studies and interior models based on these properties is essential.
This session aims to share current understanding and future developments obtained through multidisciplinary methods by inviting research on the interiors of terrestrial planets, gas giants, and ice giants, as well as their satellites. We welcome presentations from various fields, including observations, sample analysis, experiments, numerical calculations, and geophysical/chemical modeling. In addition to planets and satellites of the solar system, we also invite research on exoplanets.
