| Projektbeskrivelse: | Astrophysical systems possessing magnetic fields range from planetary
cores and stars to accretion discs and active galactic nuclei. The
magnetic fields are maintained by dynamo processes -- processes where
magnetic fields gain energy from the kinetic energy of fluid motions.
The most accessible and best studied example of an astrophysical dynamo
is the solar dynamo, which gives rise to the familiar 11 year sunspot
cycle. The purpose of this project is to perform and analyze a
simulation of sunspots and magnetic fields in the sun. Suitable
computer codes and computing time for carrying out the experiments are
available. Visualizations and animations are to be produced, using for
example IDL, NAG Explorer, Data Explorer, or NCAR Vapor Graphics. The
goal is to illustrate the mechanisms that are at work in sunspots and
magnetically active regions on the Sun. |
| Faglige perspektiver: | Training
in the use of computer simulations in physics and astrophysics.
Familiarity with the Danish Center for Scientific Computing (DCSC-KU).
