One obvious feature of the solar cycle is its variation from one cycle to another. In this article,
we review the dynamo models for the long-term variations of the solar cycle. By long-term …

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

Presented here is a review of present knowledge of the long-term behavior of solar activity
on a multi-millennial timescale, as reconstructed using the indirect proxy method. The …

The Explicit Body in Performance interrogates the avant-garde precedents and theoretical
terrain that combined to produce feminist performance art. Among the many artists …

Magnetic activity similar to that of the Sun is observed on a variety of cool stars with external
convection envelopes. Stellar rotation coupled with convective motions generate strong …

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 …

Ongoing studies in mathematical depth, and inferences fromhelioseismological'observations
of the internal solar rotation have shown up the limitations in our knowledge of the solar …

Aims. Although the time of the Maunder minimum (1645–1715) is widely known as a period
of extremely low solar activity, it is still being debated whether solar activity during that …

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 …

Magnetohydrodynamic simulations of fully convective, rotating spheres with volume heating
near the center and cooling at the surface are presented. The dynamo-generated magnetic …
