Unveiling Planetary Interiors Using Experiments at Extreme Conditions

Direct knowledge of a planet's interior remains elusive due to limited access beyond surface-level observations. This project aims to investigate planetary compositions and structures by examining the behavior of matter under the extreme conditions found deep within Earth and other, more massive, Earth-like exoplanets. Understanding our planet’s structure and evolution is crucial to assess the factors that determined its habitability and whether similar conditions exist elsewhere. We will utilize state-of-the-art high-pressure techniques, allowing for laboratory recreation and in situ characterization of deep planetary conditions, where matter may behave very differently than under ambient conditions. The primary focus of the project will be optimizing a novel sample fabrication method using a deposition platform at Sorbonne University in Paris; this platform provides the precision and reproducibility necessary for studying complex geological systems. Collaboration between institutions will facilitate knowledge exchange, particularly among the young scientists and students involved in the project. This shared knowledge will foster long-term collaboration, enabling our joint team to pursue experimental campaigns at the Linac Coherent Light Source at SLAC
