| The course is devoted to the introduction of the mechanisms responsible for the formation of the earth polar aurora. This includes the detailed excitation mechanisms of the aurora as well as the physics of the magnetosphere of the planet.
The fundamental laws of plasma physics are first detailed, so that it is not necessary to have first followed a course specifically devoted to that subject. More advanced topics such as magnetic reconnection and shock waves will be discussed later as needed for the study of the Earth magnetosphere. Excitation mechanisms of both the electron and proton aurora are described, as well as the magnetic substorm.
The solar wind is studied as magnetospheric and auroral phenomena are driven by its interaction with the space environment of the Earth. This interaction produces a shock wave and a boundary layer that surround the planet, and controls the magnetospheric configuration. Auroral phenomena also stem from that interaction and are studied in the last chapter in the framework of the Dungey cycle.
The course will be essentially based on the book of M.G. Kivelson and C.T. Russel, 'Introduction to space physics', completed with a few papers from scientific literature and other books.
