Physics and Chemistry of the Interstellar Medium

Presentation

This graduate level Lecture (PHY553B) was part of the Master of Planetary Science and Astrophysics of the University Joseph Fourier. The Lectures are divided into two large parts. During the first ~15 hours, we will review the basic physical processes needed to understand the physics and chemistry at play in the ISM. The second part, of approximately equal length, will make use of those processes to understand how some of the objects populating the ISM work. We will terminate the lecture by a non-exhaustive list of outstanding contemporary questions regarding the ISM. Lectures are in french, but all slides, problems, articles, references, etc... are in english.

Throughout the course, examples and applications are given. Some exercices are also proposed which are mainly based on publications. Some practice with numerical codes is also scheduled, where the students will explore subtleties in radiative transfer.

A standard background in quantum mechanics is assumed (Hydrogen atom, angular momentum coupling). Basics in hydrodynamics (ideal and non-ideal) is also a prerequisite even though a short introduction will always be given.
