Thousands of exoplanets have been discovered so far. Remote observations (including PLATO that is to be launched in April 2027) provide constraints on radii, masses, and atmospheric compositions, offering crucial insights into the physical and chemical properties of these worlds. Yet, without techniques long developed in the geosciences, it is impossible to fully interpret such data.

This short course will begin with an introduction to exoplanet observations, then progress through planetary structure, composition, mineralogy, cloud formation, atmospheric chemistry, and dynamics. It will highlight how methods from climate and atmosphere science, geophysics, geochemistry, and experimental petrology are applied to exoplanet research.

The aim is to provide participants with the physical understanding and computational tools needed to characterise exoplanets. The course is designed for (early-career) scientists from diverse backgrounds.
