The current understanding of astrophysical magnetic fields is reviewed, focusing on their
generation and maintenance by turbulence. In the astrophysical context this generation is …

The evolution of active regions (AR) from their emergence through their long decay process
is of fundamental importance in solar physics. Since large-scale flux is generated by the …

These lecture notes are based on a tutorial given in 2017 at a plasma physics winter school
in Les Houches. Their aim is to provide a self-contained graduate-student level introduction …

This book presents an introduction to, and modern account of, magnetohydrodynamic
(MHD) turbulence, an active field both in general turbulence theory and in various areas of …

A review of the present status of the theory of magnetic reconnection is given. In strongly
collisional plasmas reconnection proceeds via resistive current sheets, ie quasi-stationary …

A three-dimensional, self-consistent numerical model of the geodynamo is described, that
maintains a magnetic field for over 40,000 years. The model, which incorporates a finitely …

▪ Abstract We discuss current observational and theoretical knowledge of magnetic fields,
especially the large-scale structure in the disks and halos of spiral galaxies. Among other …

This paper reviews recent advances and current debates in modeling the solar cycle as a
hydromagnetic dynamo process. Emphasis is placed on (relatively) simple dynamo models …

The nonlinear evolution of magnetized Keplerian shear flows is simulated in a local, three-
dimensional model, including the effects of compressibility and stratification. Supersonic …

We present the first three-dimensional (3D), time-dependent, self-consistent numerical
solution of the magneto-hydrodynamic (MHD) equations that describe thermal convection …
