Seminar der Astrophysik / The Astrophysics Seminar


Course #6961   (SS 2007)

Elective Seminar in Experimental Physics (Advanced Studies), 6 credit points

Wahlpflichtseminar in Experimentalphysik (Hauptstudium)

Mondays, 14 ct (14:15) o'clock, HS Astronomy, Auf dem Hügel 71.
(Presentation of topics with all participants begins  Monday 16th April 2007 in HS of Astronomy.)
Supervised by all astronomy lecturers.
Organizaton: Pavel Kroupa (Tel. 73-6140,

Preparation of Talks:
Material for the seminar is provided by the supervisors (copies of papers, pens, transparencies,
slides, overhead, beamer). If you wish to use a beamer, contact your supervisor in time!

Quality of Talks:
This will be the first time that you encounter up-to-date scientific
literature in the form of research papers. Research papers
are not easy to read, and this is one of the hurdles you will need
to pass on your way to giving the talk.

A research paper typically contains references to other papers. Which of these
you should follow-up will be clarified by talking to your supervisor.
Following-up some of the cited literature will teach you how to navigate the
manifold of professional literature.

The talks ought to be prepared for the benefit of
your fellow students. Therefore this is an excellent chance to
practice your didactic skills. The aim is to communicate science.
Note: Avoid  black  or  blue  backgrounds  as  these  put  the  audience  to  sleep. 
Best is to use a simple white background with black or blue letters for the writing.

While the talks may be held in German, the supervisors strongly encourage
you to talk in English, as this benefits your training.

A variety of topics are offered:
