Learning Outcomes

On successful completion of this module students should be able to:

1. Recognise the problem posed by coronal heating and critically discuss heating models;
2. Explain the variation in coronal and solar wind structure in terms of changes in the solar magnetic field;
3. List models that can accelerate relativistic charged particles;
4. Discuss how coronal parameters can be measured;
5. Derive Parker's simple theory of the solar wind and critically discuss its limitations in the light of solar wind measurements;
6. Explain the origin of co-rotating structure in the solar wind;
7. Estimate the location of the solar wind termination shock and critically discuss limitations of the simple model used to calculate this position;
8. Recognise the important factors in Sun-planetary coupling over short and long time-scales;
9. Discuss the main features of Sun-comet coupling, discuss the strengths and weaknesses of the methods available to measure solar wind parameters and show how different methods can be combined to answer specific scientific questions.

Brief description

The course provides an in-depth treatment of the Physics of the solar atmosphere and heliosphere, including coupling between the solar wind and non-magnetised objects.
