Exoplanetary Mineralogy: Ultra-High Pressure Experiments and Calculations
Session ID#: 157895
Session Description:
The conditions at the interior of massive rocky exoplanets can largely exceed the pressures found at the Earth core, which leads to the formation of novel phases of minerals that do not occur on Earth. A detailed description of how properties of candidate minerals change at high pressure and temperature, together with a characterization of new phase transitions and equations of state, is essential to understand planet formation and evolution better. Thermodynamic and transport properties of minerals directly control the structural and thermal evolution of planetary mantles, such as the heat flux from the core and style of mantle convection. Interactions between rocks and different ices, such as water ice and ammonia, is also crucial to understand the structure of water-rich exoplanets, where layers of exotic ice phases can develop on top of rocky mantles and cores. We invite new experimental and theoretical results on the properties of minerals at the extreme pressures relevant to the cores and mantles of rocky exoplanets, with emphasis on novel chemistry, transport, and thermodynamic properties of candidate exoplanetary materials.
