Solar System Astronomy

Our research focusses on small solar system bodies, such as comets and asteroids, the material they emit to interplanetary space, and the processes leading to this emission. Small bodies are considered as remnant building blocks from the planet formation process in the early solar system. We study their physical properties and composition in order to better understand what they are made of, how they evolve with time, and how they formed.

We use data from both astronomical telescopes and from the European Space Agency’s Rosetta mission, and carry out numerical simulations to interpret the data.
