Some key concepts for linking rocky planetary interiors to their surface expressions

With the launch of the James Webb Space Telescope, we have entered a new era in the characterization of exoplanets. While pre-JWST research was largely driven by mass and radius measurements, current and upcoming spectroscopic observations of exoplanetary atmospheres offer promising new avenues to constrain the compositional state of these distant worlds. However, if the goal is to infer bulk planetary composition, traditionally linked to mass-radius measurements, it is essential to carefully assess the extent to which a planet's surface and atmosphere reflect the state of its interior. In this presentation, I will introduce key concepts that link the interiors of rocky planets to their surface expressions. These concepts have been extensively studied within the context of planetary science in our Solar System and may now have important implications for exoplanet research.
