The Sun and other stars are magnetic: magnetism pervades their interiors and affects their
evolution in a variety of ways. In the Sun, both the fields themselves and their influence on …

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

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 …

The Sun's magnetic field is the engine and energy source driving all phenomena collectively
defining solar activity, which in turn structures the whole heliosphere and significantly …

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 solar dynamo continues to pose a challenge to observers and theoreticians.
Observations of the solar surface reveal a magnetic field with a complex, hierarchical …

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 generation of a magnetic field in an electrically conducting fluid generally involves the
complicated nonlinear interaction of flow turbulence, rotation and field. This dynamo process …

Magnetism is one of the most pervasive features of the Universe, with planets, stars and
entire galaxies all having associated magnetic fields. All of these fields are generated by the …

Constraining dynamo theories of magnetic field origin by observation is indispensable but
challenging, in part because the basic quantities measured by observers and predicted by …
