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

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 …

Arguments for and against the widely accepted picture of a solar dynamo being seated in
the tachocline are reviewed, and alternative ideas concerning dynamos operating in the …

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 magnetic field of the Sun is the underlying cause of the many diverse phenomena
combined under the heading of solar activity. Here we describe the magnetic field as it …

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 …

Sunspots, dark magnetic regions occurring at low latitudes on the Sun's surface, are tracers
of the magnetic field generated by the dynamo mechanism. Recent solar dynamo models …

We propose an α Ω flux-transport dynamo for the Sun that is driven by a tachocline α-effect.
This α-effect comes from the global hydrodynamic instability of latitudinal differential rotation …

We present the results of a series of numerical experiments that investigate the transport of
magnetic fields by turbulent penetrative compressible convection. We find that magnetic flux …
