Magnetic helicity and force-free equilibria in the solar corona and in laboratory devices
(University of St Andrews, 1988) - ThesisForce-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
(University of St Andrews, 1997) - ThesisIn 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
(University of St Andrews, 1991) - ThesisThe 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
(University of St Andrews, 1991) - ThesisSolar 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
(University of St Andrews, 1998) - ThesisIn 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 ...
