The energy budget of stellar magnetic fields [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Spectropolarimetric observations have been used to map stellar magnetic fields, many of which display strong bands of azimuthal fields that are toroidal. A number of explanations have been proposed to explain how such fields might be generated though none are definitive.

Two-dimensional numerical experiments of convection. [PDF]
, 1996 PhDI report the results of numerical studies of 2-dimensional fully compressible convection of a fluid in which the dependence of the radiative conductivity on temperature T is taken as K, (V + aT -5)1 so that central regions of the layer are unstable ...

Cosmology with inhomogeneous magnetic fields [PDF]
, 2007 We review spacetime dynamics in the presence of large-scale electromagnetic fields and then consider the effects of the magnetic component on perturbations to a spatially homogeneous and isotropic universe.

On the topology of global coronal magnetic fields [PDF]
, 2014 This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Magnetic Fields of F-Type Stars [PDF]
, 2022 Magnetic fields are an observable feature of many stars, with warm, F-type stars of interest in searching for the transition from the fossil fields in hot stars to dynamos in cool stars driven by convection zones.

Influence of surface stressing on stellar coronae and winds [PDF]
, 2013 STFC funding has supported this research.The large-scale field of the Sun is well represented by its lowest energy (or potential) state. Recent observations, by comparison, reveal that many solar-type stars show large-scale surface magnetic fields that ...

Aspects of three-dimensional MHD : magnetic reconnection and rotating coronae [PDF]
, 2010 Solutions of the magnetohydrodynamic (MHD) equations are very important for modelling laboratory, space and astrophysical plasmas, for example the solar and stellar coronae, as well as for modelling many of the dynamic processes that occur in these ...
