Sunspots are the most readily visible manifestations of solar magnetic field concentrations
and of their interaction with the Sun's plasma. Although sunspots have been extensively …

We review our current understanding of sunspots from the scales of their fine structure to
their large scale (global) structure including the processes of their formation and decay …

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 …

We study the evolution of a melting front between the solid and liquid phases of a pure
incompressible material where fluid motions are driven by unstable temperature gradients …

We investigate stationary spatially localized hexagon patterns of the two-dimensional (2D)
Swift–Hohenberg equation in the parameter region where the trivial state and regular …

In this paper, we present numerical simulations of rapidly rotating Rayleigh-Bénard
convection in the Boussinesq approximation with stress-free boundary conditions. At …

We present a set of numerical simulations that model the convection zones of solar-like
stars. With this suite of numerical experiments, we explore how the nature of the convective …

This work studies two-dimensional fixed-flux Rayleigh–Bénard convection with periodic
boundary conditions in both horizontal and vertical directions and analyses its dynamics …

The last thirty years have seen great leaps forward in the subject of magnetoconvection.
Computational techniques can now explain exotic nonlinear behaviour, transition to chaos …

Intense east–west winds called zonal jets are observed in the atmospheres of Jupiter and
Saturn and extend in their deep interior. We present experimental results from a fully three …
