  • Numerical simulations of sunspot rotation driven by magnetic flux emergence 

    Sturrock, Zoe (University of St Andrews, 2017-06-23) - Thesis
    Magnetic flux continually emerges from the Sun, rising through the solar interior, emerging at the photosphere in the form of sunspots and expanding into the atmosphere. Observations of sunspot rotations have been reported ...
  • Flux-rope twist in eruptive flares and CMEs : due to zipper and main-phase reconnection 

    Priest, Eric Ronald; Longcope, D.W. (2017-01) - Journal article
    The nature of three-dimensional reconnection when a twisted flux tube erupts during an eruptive flare or coronal mass ejection is considered. The reconnection has two phases: first of all, 3D “zipper reconnection” propagates ...
  • On the stability of homogeneous steady states of a chemotaxis system with logistic growth term 

    Chaplain, Mark Andrew Joseph; Tello, J. I. (2016-07) - Journal article
    We consider a nonlinear PDEs system of Parabolic-Elliptic type with chemotactic terms. The system models the movement of a population “n” towards a higher concentration of a chemical “c” in a bounded domain Ω. We consider ...
  • Magneto-static modelling from SUNRISE/IMaX : application to an active region observed with SUNRISE II 

    Wiegelmann, T.; Neukirch, Thomas; Nickeler, D. H.; Solanki, S. K.; Barthol, P.; Gandorfer, A.; Gizon, L.; Hirzberger, J.; Riethmüller, T. L.; Noort, M. van; Rodríguez, J. Blanco; Del Toro Iniesta, J. C.; Suárez, D. Orozco; Schmidt, W.; Pillet, V. Martínez; Knölker, M. (2017-01-05) - Journal article
    Magneto-static models may overcome some of the issues facing force-free magnetic field extrapolations. So far they have seen limited use and have faced problems when applied to quiet-Sun data. Here we present a first ...
  • A relaxation model of coronal heating in multiple interacting flux ropes 

    Hussain, A. S.; Browning, P. K.; Hood, A. W. (2016-12-22) - Journal article
    Context: Heating the solar corona requires dissipation of stored magnetic energy, which may occur in twisted magnetic fields. Recently published numerical simulations show that the ideal kink instability in a twisted ...
