Theoretical Star Formation & Exoplanets

 

Research


The question about the origin of planets and life has fascinated humanity since ancient times. Until two decades ago we knew just the planets in our Solar System. Since then thousands of planets have been discovered around other stars. To our surprise these exoplanets have properties that are much different from the properties of the planets of our Solar System, challenging our understanding of how planets form. This is a vibrant and exciting field with many more discoveries to come from observing facilities like e.g. Kepler, GAIA, ALMA and the upcoming TESS and JWST.

The primary focus of our research is to understand the link between star and planet formation by developing computational models to study how protostellar discs, the cradles of planets, form and evolve under different conditions, and how giant planets form and evolve in them.


How do exoplanets form? How their formation relates to the formation of their parent stars? How do they evolve in the first few thousand years of their lives? What do they tell us about the formation of our Solar System? Do they influence the formation of terrestrial planets? Is our Solar System unique? These are some of the exciting open questions that we are trying to answer with our research.
