	Objectives
	THE COURSE IS FOCUSED ON THE ROLE OF NUCLEAR PHYSICS IN ASTROPHYSICS. KNOWLEDGE AND UNDERSTANDING: STUDENTS WILL ACHIEVE A GOOD GENERAL KNOWLEDGE OF NUCLEAR PROCESSES IN ASTROPHYSICAL ENVIRONMENT, IN PARTICULAR IN NUCLEOSYNTHESIS AND STELLAR EVOLUTION. IN THIS FRAMEWORK, STUDENTS WILL LEARN ABOUT THE EXPERIMENTAL METHODS EMPLOYED TO DETERMINE THE NUCLEAR PHYSICAL QUANTITIES OF ASTROPHYSICAL INTEREST AND THE PATH CONNECTING THEM, THROUGH APPROPRIATE ASTROPHYSICAL MODELS, TO OBSERVATIONS. APPLYING KNOWLEDGE AND UNDERSTANDING: THE CAPACITY TO APPLY KNOWLEDGE WILL BE FOSTERED THROUGH THE CALCULATION OF THE REACTION RATES OF THE RELEVANT REACTIONS IN HYDROGEN AND HELIUM BURNING STARTING FROM EXPERIMENTAL DATA AND THE COMPARISON OF THE RESULTS TO OBSERVATIONAL DATA (SOLAR NEUTRINOS AND WHITE DWARFS COMPOSITION).
