A Journey Into Planetary Interiors: Implications of Phase Transitions and Physical Properties of Planet-Forming Materials at Extreme Conditions
Session ID#: 157191
Session Description:
The extreme pressure and temperature conditions produced within terrestrial bodies profoundly influence the phase transitions and physical properties of the constituent materials that make up these bodies. Furthermore, the discovery of exoplanets with vastly different mass-radius relationships and orbital parameters relative to the terrestrial planets of our solar system provides new challenges to constraining their interior structures, dynamics, and possible chemistries, motivating a broader range of pressures and temperatures using state-of-the-art static and dynamic compression techniques, ab-initio calculations, and theoretical geodynamical modeling. The session intends to prompt discussions on the relationship between new constraints on the physical properties of planetary materials, recent astrophysical observations, and the implications for the structures and dynamic processes of solar system objects and exoplanets, thereby strengthening cooperation between the mineral physics and geodynamics communities. We encourage contributions that blend new mineral physics discoveries with numerical or geodynamical models of planetary interiors.
