Magnetic reconnection (graduate course)

Time: 2020, April 14 - June 30

Credit points: 10 ECTS

Prerequisites: basic course on plasma physics

Responsible department: Department of Physics and Astronomy, Uppsala University

This course covers the theory of Magnetic Reconnection in plasma and it's applications. A particular focus is on the space observations and numerical simulations of magnetic reconnection.

Literature: In addition to lecture notes the course will be based on the book:
Biskamp, Dieter 2000, Magnetic reconnection in plasmas, Cambridge, UK: Cambridge University Press, 2000 xiv, 387 p. Cambridge monographs on plasma physics, vol. 3, ISBN 0521582881 Magnetic Reconnection in Plasmas.
