Neutron stars are natural physical laboratories allowing us to study a plethora of
phenomena in extreme conditions. In particular, these compact objects can have very strong …

The strong magnetic field of neutron stars is intimately coupled to the observed temperature
and spectral properties, as well as to the observed timing properties (distribution of spin …

Self-sustained convective dynamos in planetary systems operate in an asymptotic regime of
rapid rotation, where a balance is thought to hold between the Coriolis, pressure, buoyancy …

A new kind of overset grid, named Yin‐Yang grid, for spherical geometry is proposed. The
Yin‐Yang grid is composed of two identical component grids that are combined in a …

We present the results of a benchmark study for a convection-driven magnetohydrodynamic
dynamo problem in a rotating spherical shell. The solutions are stationary aside from …

A steady flow of Maxwell Sutterby fluid is considered over a stretchable cylinder. The
magnetic Reynolds number is considered very high and induced magnetic and electric …

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 …

We analyse∼ 50 3-D numerical calculations of hydrodynamic dynamos driven by
convection in a spherical shell. We examine rigid and stress-free boundaries, with Prandtl …

Simulating the long-term evolution of temperature and magnetic fields in neutron stars is a
major effort in astrophysics, having significant impact in several topics. A detailed …

The correct asymptotic theory for the linear onset of instability of a Boussinesq fluid rotating
rapidly in a self-gravitating sphere containing a uniform distribution of heat sources was …
