Course content

One of the major issues in modern astrophysics concerns the analysis of the present composition of the Universe and its various constituting objects. Nucleosynthesis models aim to explain the origin of the different nuclei observed in nature by identifying the possible processes able to synthesize them. This course is an introduction to the big-bang and stellar nucleosynthesis. It includes the description of basic nuclear physics properties of relevance in nucleosynthesis processes. The nuclear mechanisms taking place during the big-bang and the various stellar burning phases are detailed. A special emphasis is given to the production of the elements heavier than iron by the so-called s-, r- and p-processes. The course includes 9 chapters, namely :
1. Introduction to Nuclear Astrophysics,
2. Properties of nuclei,
3. Nuclear reactions in stars,
4. Primordial nucleosynthesis,
5. Burning phases and related nucleosynthesis,
6. Nucleosynthesis of the elements heavier than iron,
7. The sprocess nucleosynthesis,
8. The r-process nucleosynthesis,
9. The p-process nucleosynthesis.
