    • Aspects of magnetic field theory in solar and laboratory plasmas 

      Lothian, Robert M. (University of St Andrews, 1990) - Thesis
      Using the Magnetohydrodynamic model, two problems in the behaviour of magnetic field structures are investigated. Firstly, the stability of tokamak equilibria to coupled tearing modes is calculated. Secondly, the equilibrium ...

    • WKB estimates to the critical length of twisted solar coronal loops 

      Herbert, Simon I. (University of St Andrews, 1995) - Thesis
      The solar corona exhibits many different phenomena, observable from the Earth or space. Magnetohydrodynamic stability theory provides a method of investigating these phenomena by using it to test proposed mathematical ...

    • Solar coronal stability problems 

      Hardie, Ian S. (University of St Andrews, 1993) - Thesis
      Magnetohydrodynamic stability theory provides a powerful tool for understanding and testing hypothesized mathematical and physical models of observed phenomena on the surface of the Sun. In this thesis, the problem of ...

    • Instability and wave-growth within some oscillatory fluid flows 

      Forster, Graham Keith (University of St Andrews, 1996) - Thesis
      Oscillatory fluid flows arise naturally in many systems. Whether or not these systems are stable is an important question and external periodic forcing of the flow may result in rich and complicated behaviours. Here three ...

    • The effects of magnetic fields on oscillations in the solar atmosphere 

      Evans, David J. (University of St Andrews, 1990) - Thesis
      A study has been made of wave propagation in two regions of the solar atmosphere in which magnetic forces are significant. Sunspot observations indicate a rich variety of characteristic modes of oscillation roughly divided ...
