What's inside

Syllabus

Cover the basics
If you want to talk about exoplanets, there is no miracle, you have to go through the fundamentals of astrophysics. This is why we propose that you first approach astrophysics from a more historical and fundamental point of view. How did the representation of the universe evolve? How was the modern vision of "celestial mechanics" constructed? You will have the pleasure of discovering the answers to some of these questions. However, in order to go further in this course, we will also see Kepler's three laws as well as some basic notions about protoplanetary disks, planets or star formation. In this first module, we propose to lay the foundations necessary to deal with the concept that interests us all: exoplanets.
