Learning unit contents

This course attempts to show how the formation of the solar system may have influenced the structure and composition of the different planets. Particular emphasis is being placed on planetary atmospheres. we show that these atmospheres have evolved differently, and that the appearance of life on Earth has had a major influence on our atmosphere, as we know it today.
Another course ("Atmosphere of the Earth") is based on a detailed study of the Earth's atmosphere and introduces the different concepts of atmospheric physics. These concepts are used in the "Solar system planets" course, which continues in this direction, in order to extend the scope of these physical laws to the atmospheres of the planets of the solar system (and to exoplanets). The differences between the atmospheres of the planets are directly related to how they were formed and, therefore, to the formation of the solar (stellar) system. The example of exoplanets allows us to explore more exotic atmospheres.
I. Introduction - Recaps
- The new solar system
- Definitions
- Titius-Bode's Law
- Planets of the solar system
- Planetary orbits and rotations
- Coordinate systems
- Planetary configurations
- Kepler's Law
- The N-body problem (N=1,2,3)
- Tides
- Roche's limit
- N >3 perturbation of orbits and resonance
- Energy sources of planets
 
II. Formation and evolution of the solar system
- Review of theories
- Standard model
- Evolutionary processes
- Escape and erosion
- Impacts
- Origin of water on Earth
- Surface Processes
 
III. Planetary atmospheres
- Composition
- Primitive solar nebula
- Primitive atmospheres (giant planets)
- Secondary atmosphere (Earth)
- Evolution of planetary atmospheres
 
IV. Extrasolar planets
- Detection of exoplanets and their atmosphere
- Characterization of exoplanetary atmospheres
 
An alternative to this type of teaching, depending on the number and background of the students, could be an in-depth analysis of a particular topic related to the course, for example: water in the solar system. In this case the work would consist in the preparation of a complete course of at least one hour to be presented as an oral exam

Learning outcomes of the learning unit

At the end of the course, students should be able to explain how the formation of the solar system influenced the atmospheric structure and composition of the different planets. They should be able to show that these planetary atmospheres evolved in different ways and that the emergence of life on Earth has had an dramatic effect on its atmosphere.

Additional information:

Oral exam.
Depending on the number and level of students, it may consist in a classical oral exam covering the whole course (2 questions), or in a presentation of an original personal work on a field related to the course.
In case of remote oral examination, use of MS Teams or Skype (backup solution).
