  • Catastrophe versus instability for the eruption of a toroidal solar magnetic flux rope 

    Kliem, B.; Lin, J.; Forbes, T. G.; Priest, E. R.; Toeroek, T. (2014-07-01) - Journal article
    The onset of a solar eruption is formulated here as either a magnetic catastrophe or as an instability. Both start with the same equation of force balance governing the underlying equilibria. Using a toroidal flux rope in ...
  • Development and application of a global magnetic field evolution model for the solar corona 

    Yeates, Anthony Robinson (University of St Andrews, 2009-06-24) - Thesis
    Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences. The free magnetic ...
  • Magnetic flux transport simulations : applications to solar and stellar magnetic fields 

    Cook, Graeme Robert (University of St Andrews, 2011-11) - Thesis
    Magnetic fields play a key role in a wide variety of phenomena found on the Sun. One such phenomena is the Coronal Mass Ejection (CME) where a large amount of material is ejected from the Sun. CME’s may directly affect ...
  • Magnetohydrodynamic simulations of the ejection of a magnetic flux rope 

    Pagano, Paolo; Mackay, Duncan Hendry; Poedts, Stefaan (2013-06) - Journal article
    Context. Coronal mass ejections (CME’s) are one of the most violent phenomena found on the Sun. One model to explain their occurrence is the flux rope ejection model. In this model, magnetic flux ropes form slowly over ...
  • Numerical simulations of a flux rope ejection 

    Pagano, P.; Mackay, D.H.; Poedts, S. (2015-03) - Journal article
    Coronal mass ejections (CMEs) are the most violent phenomena observed on the Sun. One of the most successful models to explain CMEs is the flux rope ejection model, where a magnetic flux rope is expelled from the solar ...
