Heidelberg Joint Astronomical Colloquium

As of Wintersemester 2016 the HJAC is organized by Ralf Klessen. Click here to forward to the HePhySTO page of HJAC.


The colloquium is organized jointly by the six astronomical institutes in Heidelberg, namely 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).

Organizer: C.P. Dullemond.
Members of the HJAC-committee: C. Pfrommer, K. Meisenheimer, R. Schmidt, H. Ludwig, R. Tuffs, C.P. Dullemond.

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 filming and video-editing is done by Emer Brady (as of SS 2015). In case of questions or complaints: final responsibility goes to Dullemond.

Please note the HePhySTO web site which is the central database of astronomy and physics related colloquia and seminars.

In the course of the semester, the videos of the colloquium will be uploaded here.
