Information for the Summer semester 20/21 

Welcome to the homepage of the Seminar on Astronomy and Astrophysics (astro830), a four-credits point elective course in the Master of Astrophysics program at the  Argelander Institute for Astronomy, at the  University of Bonn . Students give a talk and answer relevant questions afterwards, based on a recently published research paper, as suggested by the supervisors. Students should discuss the topic, the content and the presentation of their supervisor prior to giving it.

If you are having trouble finding a topic this semester please email Maude Charmetant before the registration deadline to help you resolve this. 

Time and Place
