  • On the theory of symmetric MHD equilibria with anisotropic pressure 

    Hodgson, Jonathan David Brockie (University of St Andrews, 2016) - Thesis
    In this thesis we discuss the theory of symmetric MHD equilibria with anisotropic pressure. More specifically, we focus on gyrotropic pressures, where the pressure tensor can be split into components along and across the ...
  • A comparison of global magnetic field skeletons and active-region upflows 

    Edwards, S. J.; Parnell, C. E.; Harra, L. K.; Culhane, J. L.; Brooks, D. H. (2016-01-01) - Journal article
    Plasma upflows have been detected in active regions using Doppler velocity maps. The origin and nature of these upflows is not well known with many of their characteristics determined from the examination of single events. ...
  • The energy budget of stellar magnetic fields : comparing non-potential simulations and observations 

    Lehmann, L. T.; Jardine, M. M.; Vidotto, A. A.; Mackay, D. H.; See, V.; Donati, J.-F.; Folsom, C. P.; Jeffers, S. V.; Marsden, S. C.; Morin, J.; Petit, P. (2016-10-27) - Journal article
    The magnetic geometry of the surface magnetic fields of more than 55 cool stars have now been mapped using spectropolarimetry. In order to better understand these observations, we compare the magnetic fieldt opology at ...
  • Theoretical foundation of 3D Alfvén resonances: normal modes 

    Wright, Andrew Nicholas; Elsden, Thomas William (2016-11-17) - Journal article
    We consider the resonant coupling of fast and Alfvén magnetohydrodynamic (MHD) waves in a 3D equilibrium. Numerical solutions to normal modes (∝ exp(−iωt)) are presented along with a theoretical framework to interpret them. ...
  • Coupled bulk-surface free boundary problems arising from a mathematical model of receptor-ligand dynamics 

    Elliot, Charles; Ranner, Thomas; Venkataraman, Chandrasekhar (2016-11-04) - Journal article
    We consider a coupled bulk-surface system of partial differential equations with nonlinear coupling modelling receptor-ligand dynamics. The model arises as a simplification of a mathematical model for the reaction between ...
