We present a model for a global axisymmetric turbulent dynamo operating in a galaxy with a corona that treats the parameters of turbulence driven by supernovae and by magneto-rotational instability under a common ...

Magnetic fields are ubiquitous in the universe and play an important role in variety of astrophysical phenomenon. It is thus very important to understand the origin, structure and strength of these astrophysical magnetic ...

In this paper, we present a systematic study of the force-free field equation for simple axisymmetric configurations in spherical geometry and apply it to the solar active regions. The condition of separability of solutions ...
