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 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 …

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 …

High-resolution images of the solar surface show a granulation pattern of hot rising and
cooler downward-sinking material–the top of the deep-reaching solar convection zone …

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 use the anelastic spherical harmonic code to model the convective dynamo of solar-type
stars. Based on a series of 15 3D MHD simulations spanning four bins in rotation and mass …

This article surveys the development of observational understanding of the interior rotation
of the Sun and its temporal variation over approximately forty years, starting with the 1960s …

We present three-dimensional nonlinear magnetohydrodynamic simulations of the interiors
of fully convective M dwarfs. Our models consider 0.3 solar-mass stars using the Anelastic …

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 …

A review of solar cycle prediction methods and their performance is given, including early
forecasts for Cycle 25. The review focuses on those aspects of the solar cycle prediction …
