    • Magnetic helicity and force-free equilibria in the solar corona and in laboratory devices 

      Dixon, Andrew Michael (University of St Andrews, 1988) - Thesis
      Force-free equilibria are believed to be important in both an astrophysical and a laboratory context as minimum-energy configurations (see, for example, Woltjer, 1958; Taylor, 1974). Associated is the study of magnetic ...
    • MHD flows in the solar atmosphere 

      Del Zanna, Luca (University of St Andrews, 1997) - Thesis
      In this thesis, different aspects of the physics of flows in the solar atmosphere are examined. These are described by means of the set of (ideal) magnetohydrodynamics (MHD) and throughout the thesis there is a progressive ...
    • The nonuniform magnetohydrodynamic nature of the solar atmosphere 

      De Ville, Andrew (University of St Andrews, 1991) - Thesis
      The nonuniform structure observed in the solar atmosphere, and in particular the corona, is thought to arise due to the interaction between the magnetic field and plasma. Using a linear theory, the nature of these interactions ...
    • Aspects of solar coronal stability theory 

      De Bruyne, Peter J. J. (University of St Andrews, 1991) - Thesis
      Solar coronal stability theory is a powerful tool for understanding the complex behaviour of the Sun's atmosphere. It enables one to discover the driving forces behind some intriguing phenomena and to gauge the soundness ...
    • The influence of thermal and magnetic layers on solar oscillation frequencies 

      Daniell, Mark (University of St Andrews, 1998) - Thesis
      In this thesis, a study is made of the global solar oscillations known as p-modes, modelled by a plane-parallel stratified plasma, within which is embedded a horizontal layered magnetic field. A magnetohydrodynamic formalism ...
