Exoplanets and planet formation

Using observations from ground-based and space observatories, along with state-of-the-art theoretical modeling, we study protoplanetary disks, exoplanets and their atmospheres. Ultimately, we are working on addressing the key question - how common are planets that might harbor life?

Introduction

Studying young stars enables us to investigate all stages of planet formation :

- planet-forming disks,
- dust and debris disks
- and the youngest protoplanets.

The study of exoplanetary atmospheres has greatly enhanced our ability to investigate the properties of planets and planetary systems around more mature stars. With more detailed observations, we improve our theoretical understanding of how planets form and evolve. We study:

-the composition, dynamics and habitability of exoplanet atmospheres
-the evolution of exoplanets through atmospheric escape

Disk and Planet Formation research group

We focus on the evolution of protoplanetary disks through all stages of planet formation. Specifically, in past years, significant results have been achieved in understanding :

- the chemistry, geometry and dynamics of planet-forming disks through theoretical modelling and imaging and spectroscopy campaigns
-various aspects of pebble accretion in the growth of planetary bodies

Exoplanet Research Group

We pursue research into the chemistry, structure and dynamics of exoplanet atmospheres.

A key area of expertise is spectroscopic observations from the ultraviolet to the infrared wavelength range, using some of the world’s most powerful observational facilities.

Theoretical work includes detailed characterization of exoplanet atmospheres from their observed spectra, connecting the properties of planets to their formation and evolution mechanisms.
