Astrophysical magnetohydrodynamics

In this course you will learn about flows of neutral fluids and plasma in astrophysics.

You will study the dynamics of magnetised gases, also known as the theory of magnetohydrodynamics (MHD). Such magnetised flows are common in astrophysics, for example in the Sun and the solar wind, but also in accretion disks around stars, and in the interstellar medium. Through the course you will explore the basic equations of MHD, the different types of waves and instabilities which occur in such flows, turbulence and the dynamo effect in which magnetised flows amplify their magnetic fields. You will also apply these concepts  to the Sun and other astrophysical systems.


  • Course structure

    The course is given during day time, at 50% pace. It is part of the Master’s program in Astronomy, but can also be taken as a free-standing course. The course is normally given in English.


    Teaching format

    Blackboard lectures and tutorials.
