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 …

We investigate the properties of a kinematic flux transport solar dynamo model. The model is
characterized by a solar-like internal differential rotation profile, a single-cell meridional flow …

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 …

Theoretical models for the solar dynamo range from simple low-dimensional “toy models” to
complex 3D-MHD simulations. Here we mainly discuss appproaches that are motivated and …

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 …

This paper presents a series of helioseismic inversions aimed at determining with the
highest possible confidence and accuracy the structure of the rotational shear layer (the …

We investigate the e† ect of stochastic—uctuations on a—ux transport model of the solar
cycle based on the Babcock-Leighton mechanism. Speci–cally, we make use of our recent …
