Astrofysikalisk magnetohydrodynamik, 7,5 hp

Om kursen

The course explores 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 black holes and in the interstellar medium. It covers 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. Applications of these concepts to the Sun and other astrophysical systems are also contained in the course.
