Study Programmes 2015-2016
ASTR0204-2  
Astrophysics and geophysics
Duration :
30h Th, 30h Pr
Number of credits :
Bachelor in physics6
Bachelor in physics6
Lecturer :
Marc-Antoine Dupret
Language(s) of instruction :
French language
Organisation and examination :
Teaching in the first semester, review in January
Units courses prerequisite and corequisite :
Prerequisite or corequisite units are presented within each program
Course contents :
Astrophysics: The main physical processes in the description of stars and their evolution are put in evidence. The study of the extra-galactic universe is considered with main attention to the expansion of the universe and the Hubble law.
Geophysics: We present the internal structure of the Earth and the way to probe it with seismic waves. The physical and chemical properties of the atmosphere are discussed and we establish the energetic balance of the earth. Recent problems: greenhouse effect, stratospheric ozone are detailled.
Astronomy: The way to locate stars in the celestial sphere is detailed, as well as their apparent motions (diurnal, annual, precession). A particular attention is given to the seasons phenomenon. Finally, the important problem of the distance determination in astronomy is considered.
Learning outcomes of the course :
The aim of the part "Astrophysics" is to introduce students to the main components of our universe: stars, galaxies, large scale universe. Of particular importance is the understanding of the underlying fundamental physics processes.

The aim of the part "Géophysics" is on the one hand to give an overview of the internal structure of our Earth. On the other hand, a particular attention is given to the physical and chemical description of the atmosphere. Opening the gate to a precise understanding of important subjects such as the greenhouse effect and the question of the stratospheric ozone is of particular importance.

Finally, the aim of the part "Astronomy" is to give students basic elements for a better knowledge of the apparent univers and to understand the link between observations and the geometrical characteristics of our univers.
Prerequisite knowledge and skills :
Basic knowledges in physics, thermodynamics and mechanics are essential. Basic mathematical knowledges, particularly in trigonometry are also required.
The following courses are prerequired:
- Physique moderne, L. Dreesen (bac2 physics)
- Thermodynamique, N. Vandewalle (bac2 physics)
Planned learning activities and teaching methods :
The exercices are organised as sessions of 2h30.
Mode of delivery (face-to-face ; distance-learning) :
The course is given the first semester (2 times 2h30 / week), including the exercise sessions.
Recommended or required readings :
Complete notes, as well as the powerpoint presentations are available, see:

Assessment methods and criteria :
An oral (theory) and written (exercises) exam is organised during the january session.
