Module Aims: To treat the physics of the stellar interior and the underlying fundamental processes and parameters. To introduce the topics of star formation and stellar atmosphere physics. To introduce different models developed for the explanation of the stability, dynamics and evolution of the stars.

Learning Outcomes

1. Outline and discuss the physical concepts relating to the stability of stellar structure. Solve analytically related problems.
2. Discuss the modalities of the comparison between theoretical models and observations, with applications to specific cases.
3. Describe and illustrate the different fusion reactions dominating the different phases of stellar evolution. Solve related problems.
4. Describe the main physical principles regulating stellar atmospheres and solve analytically simplified problems.
5. Discuss the evolutionary phases of stars of different masses.
6. Discuss the role of compact objects and supernovae in the evolution of binary stars and the consequences on galactic evolution.
7. Demonstrate oral communication skills
