PHYS6004 Space Plasma Physics
The aim of this course is to explore the physical processes which occur in the space environment. Theories of solar wind propagation and its interaction with the earth are developed and compared with data from satellites and ground based observatories. The course will provide a brief revision of key elements of electromagnetic theory. Magnetohydrodynamics (MHD) will be developed and applied, with application of kinetic theory to areas where MHD breaks down. The reasons why space plasma physics is important for modern day life will be discussed. The magnetospheres of other planets will be compared to Earth’s.
