Learning unit contents

Planetary magnetospheres and Aurorae

Polar aurorae do not only exist on Earth. They also appear on other planets and other objects in our Solar System and even in other planetary systems. These phantom-like displays are the most impressive evidence of permanent interaction between the planets and their spatial environment. In most cases, this interaction results from the combination of the Sun-Magnetosphere-Ionosphere. Other combinations exist and are just as effective at producing aurorae. We will explore the Solar System looking for such combinations.

A large part of the course is devoted to the Planeterrella experiment. This experiment illustrates many aspects of plasma physics as applied to auroras and planetary magnetospheres. Students will have the opportunity to work with the apparatus during practical sessions. The final examination will include an individual presentation of the results of this experiment (carried out in groups).

Prerequisite knowledge and skills

Corequisite: SPAT0055 (or SPAT0048)
(It might be useful to follow courses SPAT0001, SPAT0029)

Planned learning activities and teaching methods

Problems and practical work

Students will have the opportunity to conduct the Planeterralla experiment, which is a simulator of auroras and magnetospheric configurations. Using the equipment provided, they will be able to verify laws such as Paschen's law and determine the origin of auroral emissions (using a multi-channel spectrometer). An individual report on this experiment will be presented during the oral examination.

 

Mode of delivery (face to face, distance learning, hybrid learning)

Blended learning


Additional information:

A recorded version (MP4) of all lectures is available on Vimeo (links provided).
If it is not possible to organize practical work sessions based on the use of planeterrella, these group work sessions will be replaced by individual analysis of an article to be selected from a list made available to students. These articles are available on eCampus in pdf format.

Additional information:

The oral examination consists of a presentation of the individual report on the Planeterrella experiment, in French or English. Students have approximately 15 minutes to present the content of their report, what they have learnt from it, and to attempt to link it to the material covered in the course.

Questions will be asked about both the report and the material covered in the course. Assessment will be based on:

- the mastery of the material presented (20%),

- the highlighting of links with the course (15%),

- the quality and care of the presentation (15%) and

- the relevance of the answers to the questions (50%).  

 

In case of remote oral examination, use of MS Teams (backup solution).
