An experimental approach to investigate carbon rich exoplanets interior
Abstract
We experimentally determined properties (i.e. phase assemblage, thermal equation of state, melting temperature) of carbides (Si-C, Fe-Si-C) under extreme pressure and temperature conditions to constrain internal properties of carbon-rich exoplanets. By expanding the P-T-X range of these measurements, we can tightly constrain the phase diagram of binary and ternary carbide systems, and establish accurate PV- T equation of state. Our experimental results are critically important for building reliable direct models for the interiors of exoplanets as well for interpreting observational data from recently launched survey missions such as TESS.
