Learning unit contents
This course is a direct continuation of the course: "Structure et Evolution des Etoiles I".The theoretical background presented in the first part allows us now to explore the different phases of stellar evolution, putting the emphasis on the underlying physical processes. The use of homologous transformations allows us to understand the main tendencies and to quantify the importance of each physical aspect. Each phase of a stellar "life" is analysed in details: the initial phase of gravitational contraction, the main sequence (hydrogen fusion), the next red giant phases and the end of the story (white dwarfs, supernovae, neutron stars, black holes). The course is not limited to a simple description of each phase, the aim is to explore the key physical processes and causes at the origin of the stellar structure evolution in one or another direction. The different scenarios of evolution depending on the stellar mass are justified in detail. The critical phases of stellar evolution, when new nuclear reaction set off, are analysed, as well as the resulting nucleosynthesis. Stars are indeed the great creators of the universe, synthesizing all chemical elements of the universe heavier than helium.
Learning outcomes of the learning unit
Knowing and understanding the main phases of a stellar life. An exhaustive and "descriptive" knowledge is not looked for. Instead, what imports here is a precise understanding of the underlying physical processes and their respective importance.
Prerequisite knowledge and skills
To have followed the course "Structure et Evolution des Etoiles I" (SPAT 0044-1), which is a "co-required".
Planned learning activities and teaching methods
Mode of delivery (face-to-face ; distance-learning)
The lectures are given second semester, 2-3/week.
From the academic year 2015-2016, the lectures are given in English if there is at least one student attending the lectures who does not speak French. If all students speak French, the lectures are given in French.
Recommended or required readings
Detailed lecture notes are available to students as well as the powerpoint slides of the lectures. The students can find them on my web site: http://www.astro.ulg.ac.be/~dupret
Assessment methods and criteria
A list of possible questions covering the most important aspects of the course is provided (and commented) at the end of the semester. The student must answer one of them (drawn randomly) during the oral exam, he can choose to answer in English or French.

Adaptation of teaching commitments following the COVID-19 pandemic for the May-June 2020 session
Teaching methods implemented : distance-learning
When distance teaching started, I first gave 2 lectures with Lifesize. But because significant connection problems occurred during the second one, I next decided to proceed differently. I recorded the lectures in advance with Camtasia and sent them to the student via DoX. Teaching is replaced by question-answers sessions in visioconf at the schedule of the course.
Assessment subjects
The whole matter could be given.
Assessment methods
A list of 6 questions covering most of the matter was sent to the students in advance. They are invited to choose 1 question from among these and prepare 1 presentation (powerpoint, pdf, ...) in advance answering it. During the oral exam, they will give this presentation by videoconference in 20 minutes with screen sharing, and, based on this, I will then ask them for details to make me aware of their level of understanding. I will then ask 1 or 2 short questions on another part of the matter to verify that the student has not limited him/herself in his/her study to the part presented.
