English language
Organisation and examination :
Teaching in the first semester, examination in June
Units courses prerequisite and corequisite :
Prerequisite or corequisite units are presented within each program
Learning unit contents :
These lectures establish the theoretical bases allowing us to describe stellar structure and evolution. Their state of hydrostatic and sometimes thermal equilibrium, as well as the energy transport processes are put in equations. Some recalls of statistical physics allow us to consider the degenerate condition of the electron gas, which plays a key role in stellar evolution. Recalls of nuclear physics are made and followed by a study of the different thermonuclear reactions playing a role during a stellar "life". The main interaction processes between matter and radiation are examined. A mathematical analysis of polytropic gaseous spheres leads us to the notions of limiting mass and mass-radius relation. Finally, we describe very briefly the main phases of stellar evolution.
Learning outcomes of the learning unit :
Knowledge and understanding of the physical conditions of stellar interiors. Link with the different domains of physics.
Prerequisite knowledge and skills :
Basic notions in fluid mechanics, quantum physics, statistical physics and thermodynamics.
This course has no co-required.
Planned learning activities and teaching methods :
Mode of delivery (face-to-face ; distance-learning) :
The lectures are given first semester, 2h15/week.
From the academic year 2016-2017, it is given in English, except if the students ask it to be in French.
Recommended or required readings :
Complete notes are available.
Assessment methods and criteria :
During the oral exam each student presents, in about 20 minutes, a question of his/her choice considered during the course. He/she is also briefly questioned about other aspects of the course.
