Course Outline: 

Solar-Terrestrial physics is the study of the interaction of the solar wind and the Earth’s magnetosphere. Interplanetary space and Geospace are in the plasma state. The gross dynamics of the region can be studied by the methods of magnetohydrodynamics (MHD). In this course the basic equations of MHD are developed and applied to the dynamics of the solar corona, solar wind, the bow shock and the magnetosphere. This allows an understanding of space weather, which is of great importance in modern satellite technology.


  • Basic equations of MHD.
  • Equilibrium and the steady state.
