    • Magnetohydrostatic modelling of stellar coronae 

      MacTaggart, David; Gregory, Scott; Neukirch, Thomas; Donati, Jean-Francois (2016-02-11) - Journal article
      We introduce to the stellar physics community a method of modelling stellar coronae that can be considered to be an extension of the potential field. In this approach, the magnetic field is coupled to the background ...
    • On magnetic reconnection and flux rope topology in solar flux emergence 

      MacTaggart, David; Haynes, Andrew Lewis (2014-02-21) - Journal article
      We present an analysis of the formation of atmospheric flux ropes in a magnetohydrodynamic solar flux emergence simulation. The simulation domain ranges from the top of the solar interior to the low corona. A twisted ...
    • Simulating the "Sliding Doors" Effect Through Magnetic Flux Emergence 

      MacTaggart, David; Hood, Alan William (2010-06-04) - Journal article
      Recent Hinode photospheric vector magnetogram observations have shown that the opposite polarities of a long arcade structure move apart and then come together. In addition to this "sliding doors" effect, orientations of ...
    • Theoretical magnetic flux emergence 

      MacTaggart, David (University of St Andrews, 2011) - Thesis
      Magnetic flux emergence is the subject of how magnetic fields from the solar interior can rise and expand into the atmosphere to produce active regions. It is the link that joins dynamics in the convection zone with ...
