  • Effect of structuring on coronal loop oscillations 

    McEwan, Michael P. (University of St Andrews, 2007-06) - Thesis
    In this Thesis the theoretical understanding of oscillations in coronal structures is developed. In particular, coronal loops are modelled as magnetic slabs of plasma. The effect of introducing inhomogeneities on the ...
  • MHD mode conversion of fast and slow magnetoacoustic waves in the solar corona 

    McDougall-Bagnall, A. M. Dee (University of St Andrews, 2010-11-30) - Thesis
    There are three main wave types present in the Sun’s atmosphere: Alfvén waves and fast and slow magnetoacoustic waves. Alfvén waves are purely magnetic and would not exist if it was not for the Sun’s magnetic field. The ...
  • MHD simulations of coronal heating 

    Tam, Kuan V. (University of St Andrews, 2014-12-01) - Thesis
    The problem of heating the solar corona requires the conversion of magnetic energy into thermal energy. Presently, there are two promising mechanisms for heating the solar corona: wave heating and nanoflare heating. In ...
  • A non-linear force-free field model for the solar magnetic carpet 

    Meyer, Karen Alison (University of St Andrews, 2012-06-22) - Thesis
    The magnetic carpet is defined to be the small-scale photospheric magnetic field of the quiet Sun. Observations of the magnetic carpet show it to be highly dynamic, where the time taken for all flux within the magnetic ...
  • Numerical simulations of footpoint driven coronal heating 

    O'Hara, Jennifer (University of St Andrews, 2016-06-24) - Thesis
    Magnetic field permeates the solar atmosphere and plays a crucial role in the dynamics, energetics and structures observed. In particular, magnetic flux tubes provide the structure for coronal loops that extend from the ...
  • The period ratio P₁/2P₂ in coronal waves 

    Macnamara, Cicely K. (University of St Andrews, 2011-11-30) - Thesis
    Increasing observational evidence of wave modes brings us to a closer understanding of the solar corona. Coronal seismology allows us to combine wave observations and theory to determine otherwise unknown parameters. The ...
  • Topological structure of the magnetic solar corona 

    Maclean, Rhona Claire (University of St Andrews, 2007) - Thesis
    The solar corona is a highly complex and active plasma environment, containing many exotic phenomena such as solar flares, coronal mass ejections, prominences, coronal loops, and bright points. The fundamental element ...
  • Wave propagation, phase mixing and dissipation in Hall MHD 

    Threlfall, James W. (University of St Andrews, 2012-06-22) - Thesis
    In this thesis the effect of the Hall term in the generalised Ohm’s law on Alfvén (shear) and fast wave propagation and dissipation in the ion cyclotron frequency range is investigated. The damping of an initially ...
