  • Collisionless current sheet equilibria 

    Neukirch, Thomas; Wilson, Fiona; Allanson, Oliver Douglas (2018-01) - Journal article
    Current sheets are important for the structure and dynamics of many plasma systems. In space and astrophysical plasmas they play a crucial role in activity processes, for example by facilitating the release of magnetic ...
  • Current sheets in the solar corona : formation, fragmentation and heating 

    Bowness, Ruth (University of St Andrews, 2011-11-30) - Thesis
    In this thesis we investigate current sheets in the solar corona. The well known 1D model for the tearing mode instability is presented, before progressing to 2D where we introduce a non-uniform resistivity. The effect ...
  • Equilibrium and dynamics of collisionless current sheets 

    Harrison, Michael George (University of St Andrews, 2009-06-24) - Thesis
    In this thesis examples of translationally invariant one-dimensional (1D) Vlasov-Maxwell (VM) equilibria are investigated. The 1D VM equilibrium equations are equivalent to the motion of a pseudoparticle in a conservative ...
  • 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 ...
  • On the nature of reconnection at a solar coronal null point above a separatrix dome 

    Pontin, D. I.; Priest, E. R.; Galsgaard, K. (2013-09-10) - Journal article
    Three-dimensional magnetic null points are ubiquitous in the solar corona and in any generic mixed-polarity magnetic field. We consider magnetic reconnection at an isolated coronal null point whose fan field lines form a ...
  • On the relationship between equilibrium bifurcations and ideal MHD instabilities for line-tied coronal loops 

    Neukirch, T.; Romeou, Z. (2010-01) - Journal article
    For axisymmetric models for coronal loops the relationship between the bifurcation points of magnetohydrodynamic (MHD) equilibrium sequences and the points of linear ideal MHD instability is investigated, imposing line-tied ...
