How do planets and planetary systems
come into being?

I study critical aspects of star- and planet formation, which cross the boundaries of
astro- and geophysics. To do so, I employ numerical and semi-analytical approaches, like N-body
and fluid dynamic models. Please find an introduction to some of my projects below.

Supernova pollution of forming planetary systems

We model the injection of short-lived radioisotopes into recently formed planetary systems by the ejecta of supernovae. Our predictions hint on a dichotomy of systems: many systems with low abundances versus few with excess abundances.

Thermo-mechanical evolution of planetesimals

The thermal history and internal structure of early-formed planetesimals yield important implications for the final composition and evolution of terrestrial planets. In this study we assess the influence of the abundance of short-lived radionuclides, the formation time and size of planetesimals in a systematic study.
