EXPLORING THE PROPERTIES OF PLANETARY INTERIORS USING EXPERIMENTAL TECHNIQUES

Exploring the physical properties of minerals and melts within planetary interiors is essential for understanding the conditions of planetary formation, evolution, and dynamics. In this presentation, we will delve into the experimental techniques used to investigate these properties, highlighting our recent findings on how light elements influence the physical properties of planetary cores. Using large volume presses, including the Paris-Edinburgh press and multi-anvil apparatus, we examine how the liquid structure and melting point of Fe-alloys change as a function of light element content. Additionally, we use diamond anvil cells to investigate the high-pressure stability and anisotropy of Fe and Fe compounds. Each experimental technique provides unique insights, contributing to a comprehensive understanding of planetary interiors.
