  • Can magnetic breakout be achieved from multiple flux emergence? 

    MacTaggart, David; Hood, Alan W. (EDP Sciences, 2009-07)
    Aims. We study the breakout model using multiple flux emergence to produce the magnetic configuration and the trigger. We do not impose any artificial motions on the boundaries. Once the original flux tube configuration ...
  • Finite deformation in ideal magnetohydrodynamics 

    MacTaggart, David (EDP Sciences, 2012-06)
    Aims: In this paper we investigate the finite deformation of magnetic fields that can enable one to find complex analytical magnetohydrostatic (MHS) equilibria. These can be used as input to non-linear simulations. Methods: ...
  • Multiple eruptions from magnetic flux emergence 

    MacTaggart, David; Hood, Alan W. (EDP Sciences, 2009-12)
    Aims. In this paper we study the effects of a toroidal magnetic flux tube emerging into a magnetized corona, with an emphasis on large-scale eruptions. The orientation of the fields is such that the two flux systems are ...
  • Non-symmetric magnetohydrostatic equilibria: a multigrid approach 

    MacTaggart, David; Elsheikh, A.; McLaughlin, J. A.; Simitev, R. D. (EDP Sciences, 2013-07-23)
    Linear magnetohydrostatic (MHS) models of solar magnetic fields balance plasma pressure gradients, gravity and Lorentz forces where the current density is composed of a linear force-free component and a cross-field component ...
  • On the emergence of toroidal flux tubes: general dynamics and comparisons with the cylinder model 

    MacTaggart, David; Hood, Alan W. (EDP Sciences, 2009-11)
    Aims. In this paper we study the dynamics of toroidal flux tubes emerging from the solar interior, through the photosphere and into the corona. Many previous theoretical studies of flux emergence use a twisted cylindrical ...
