    • Equilibrium and stability properties of collisionless current sheet models 

      Wilson, Fiona (University of St Andrews, 2013-06-28) - Thesis
      The work in this thesis focuses primarily on equilibrium and stability properties of collisionless current sheet models, in particular of the force-free Harris sheet model. A detailed investigation is carried out into ...
    • Instability in internal solitary waves with trapped cores 

      Carr, Magda; King, Stuart Edward; Dritschel, David Gerard (2012-01) - Journal article
      A numerical method that employs a combination of contour advection and pseudo-spectral techniques is used to investigate instability in internal solitary waves with trapped cores. A three-layer configuration for the ...
    • Finite and infinite ergodic theory for linear and conformal dynamical systems 

      Munday, Sara (University of St Andrews, 2011-11-30) - Thesis
      The first main topic of this thesis is the thorough analysis of two families of piecewise linear maps on the unit interval, the α-Lüroth and α-Farey maps. Here, α denotes a countably infinite partition of the unit interval ...
    • The propagation and damping of slow magnetoacoustic waves in the solar atmosphere 

      Owen, Nicholas Robert (University of St Andrews, 2012-11-30) - Thesis
      The propagation and damping of slow magnetoacoustic waves in the solar atmosphere is investigated, with particular emphasis placed on waves with periodicities of five minutes. The basic model of a uniform temperature ...
    • 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 ...
