The evolution of dynamo maintained magnetic fields in a barred spiral galaxy.

MOSS D., KORPI M., RAUTIAINEN P. and SALO H.

Abstract (from CDS):

We model the evolution of dynamo maintained magnetic fields in a barred spiral galaxy. The velocity fields are taken from N-body dynamical simulations. The important feature is the presence of strong, unsteady non-circular gas motions, driven by the central bar, The nonlinear dynamo calculations are carried out with both two dimensional (thin disc approximation) and three dimensional codes. The resulting magnetic field shows repeated episodes with approximately ring-like structure, and structure with short spiral arms. These morphological features appear robust, in that velocity data from distinct dynamical simulations gives rise to similar structures.
