Registration: Please register for the lecture, tutorial group.

 

Location:

The lecture and the tutorials will probably be held in person in the Kleiner Hörsaal, Philosophenweg 12.

 However, due to the uncertain Covid-19 situation this may change.

 

 

Lecture: Thursdays, 14:15-15:45

Please submit the homework solutions online at this webpage. The link is found under 'My Groups' (and the selection of the lecture/group). The upload interface offers the possibility to hand in the homework together with other students from the group. The homework solutions need to be handed in by noon on Wednesday the week after they have been issued. 

 

Please wear a mask during the lecture, exercises and the seminar!

Seminar

 

The papers for the seminar can be found under 

https://ui.adsabs.harvard.edu/public-libraries/uN4o-kg5TeW10Z8mHRg95w
 
Please choose until July 5 three topics with first, second, and third priority and send your choice to jordan@ari.uni-heidelberg.de. Please put "Stellar Astrophysics Seminar" into your Email subject.
 
Note that some papers are dealing with the same topic, e.g. "A gap in the lower main sequence ..." and "A closer look at the transition ...". In this case, you should use both papers.
 
There are several suggestions for Review papers dealing with a larger field in astronomy. In these cases please limit yourself to what you find most interesting.
 
As soon as we know how many of you will participate in the seminar we will discuss whether we need two or three days and how long the talks should be. 
 
The Seminar will take place in from August  3-5, 2022, 9:00-17:00 CEST. All participants need to be present for the full seminar. The details will be discussed in the lecture.
 
Preliminar sequence of the seminar talks
The talks are not scheduled to a specidic day, because it is not easily predictable how long we will need.
