Degrees incorporating this pedagocial element :


This course will teach students to:

- Recognise the nature of a star according to observations, deduce its mass, and be able to describe its structure and past and future evolution
- Place a star in an H-R diagram
- Master the physical principles underlying the stellar structure: what is the state of the matter according to the physical characteristics (EOS)? What is the dominant transport process?
- Understand the basics of stellar evolution: why does evolution take place? What are the timescales?
- Perform simple calculations: comparison with the Sun, estimate Tc and ρc, polytropes, approved models
- They will also gain an introduction to a few stellar physics research fields.

It is based on the following plan:
First part: Stellar structure: General information on stars, observations vs physical parameters. Basic equations of stellar structure. Energy transport (radiation/conduction/convection). Thermodynamics and equation of state (abundance, mean molecular weight, state of matter, etc.)

Second part: Stellar evolution:  General principle of stellar evolution (characteristic evolution times; collapse, etc.) Star formation (place of formation; gravitational collapse) Pre-main sequence, main sequence and post-main sequence evolution.

Recommended prerequisite

Statistical physics, thermodynamics
