Each student is expected to give a presentation of 15 minutes, to discuss a recent research paper on a topic in nucleosynthesis. A list of suggested papers is available here.

NOTE: if the paper file is compressed (ends with .gz), it has already been chosen by somebody.

The setup of the lectures is as follows: in the lectures, it is assumed that you worked through the corresponding chapter of the day (see table below). During the lecture, we will discuss the most relevant issues of the lectures, and the most relevant questions you have about the lecture topic. You need to email me your questions before Wednesday 13:00 to Debashis Sanyal and Luca Grassitelli ( and so that they can be considered for the Thursday and Friday lectures. In your email, please use "NucSyn" as subject, and mention at the beginning of your question the corresponding subsection of the lecture notes. Note that 50% of the grade for this lecture will be based on your questions. The other half will be based on your presentation. Your presence in the lectures, and in the excercise class, is also a requirement to earn the credit points for this class.
