    • Nonlinear magnetic reconnection 

      Colin, A. M. (University of St Andrews, 1987) - Thesis
      In many astrophysical problems magnetic reconnection plays a major role. Despite this reconnection theory remains incompletely understood, partly due to the strong non-linearity of the governing equations and the resulting ...

    • The nonlinear thermal evolution of coronal structures 

      Mendoza Briceño, César Augusto (University of St Andrews, 1996) - Thesis
      The thermal equilibrium and evolution of coronal structure is studied in this thesis. A symmetric and constant cross-sectional coronal loop is considered and, because of the strong magnetic field, the plasma is confined ...

    • Exact solutions for axisymmetric and nonpolytropic astrophysical winds 

      Lima, João José de Faria Graça Afonso (University of St Andrews, 1995) - Thesis
      Astrophysical outflows are common in a large variety of objects with very different length-scales. They can be almost spherical, as in the case of the solar wind, or show a high degree of anisotropy as in pre-main sequence ...

    • Chromospheric effects on global solar oscillations 

      Johnston, Alan (University of St Andrews, 1994) - Thesis
      A study has been made of the global solar oscillations known as p-modes. The Sun is represented by a plane-parallel stratified plasma. Solutions are found to the magnetohydrodynamic equations of motion in such a plasma, ...

    • Theoretical modelling of global oscillations in solar prominences 

      Joarder, Parthasarathi (University of St Andrews, 1994) - Thesis
      This thesis aims to provide a basic theoretical explanation for the oscillatory motions observed in solar quiescent prominences. The prominence is treated as a simple plasma slab embedded in a hotter and rarer uniform ...
