Joachim Wiegert

Doktorand at Department of Earth and Space Sciences, Radio Astronomy and Astrophysics

Studies of exoplanetary systems. In particular I study circumstellar dust discs by forming accurate models to observations. From this we learn about the configuration and evolution of other systems, and we put the solar system into a wider context.
