Heidelberg Joint Astronomical Colloquium

The Heidelberg Joint Astronomical Colloquium typically takes place on Tuesdays at 16h in the Grand Lecture Hall of the old Physics Building at Philosophenweg 12. Due to the global Corona pandemic the colloquium is currently held via zoom. The current schedule is available at HePhySTO (

There is a special HJAC youtube channel you can visit. This will always feature the most recent talks plus all previous ones. There is a possibility to subscribe to this channel. The final responsibility for the time of winter semester 2009/2010 to winter semester 2015/2016 goes to H.-G. Ludwig and N. Christlieb, for the period of winter term 2012/2013 to summer term 2016 it goes to C. Dullemond, for the time of winter semester 2016/2017 to summer semester 2019 it goes to R. Klessen, for the time of winter term 2019/2020 to winter term 2020/2021 it goes to D. Kruijssen. Since summer term 2021, the colloquium organisers are R. Tuffs and R. Klessen.

The colloquium is organized jointly by the six astronomical institutes in Heidelberg. These are Astronomisches Rechen-Institut (ARI), Institut für theoretische Astrophysik (ITA), Landessternwarte (LSW), Max-Planck Institute für Astronomie (MPIA), Max-Planck Institut für Kernphysik (MPIK), and the Heidelberg Institute for Theoretical Studies (HITS).
