    • Coronal heating by the partial relaxation of twisted loops 

      Bareford, Michael; Hood, Alan; Browning, Philippa (2013-02) - Journal article
      Context: Relaxation theory offers a straightforward method for estimating the energy that is released when a magnetic field becomes unstable, as a result of continual convective driving. Aims: We present new results obtained ...
    • Coronal heating in multiple magnetic threads 

      Tam, Kuan Vai; Hood, Alan William; Browning, Philippa; Cargill, Peter (2015-08) - Journal article
      Context. Heating the solar corona to several million degrees requires the conversion of magnetic energy into thermal energy. In this paper, we investigate whether an unstable magnetic thread within a coronal loop can ...
    • Energy release in driven twisted coronal loops 

      Bareford, Michael R; Gordovskyy, Mykola; Browning, Philippa; Hood, Alan William (2016-01) - Journal article
      Magnetic reconnection in twisted magnetic flux tubes, representing coronal loops, is investigated. The main goal is to establish the influence of the field geometry and various thermodynamic effects on the stability of ...
    • Inhomogeneous magnetic fields in the solar atmosphere 

      Browning, Philippa (University of St Andrews, 1984) - Thesis
      The magnetic field in the solar atmosphere is highly inhomogeneous. In the photosphere, the field is concentrated into intense flux tubes and the coronal magnetic field consists of many loops and regions of open field. ...
    • An MHD avalanche in a multi-threaded coronal loop 

      Hood, Alan William; Cargill, Peter; Browning, Philippa; Tam, Kuan (2016-01-18) - Journal article
      For the first time, we demonstrate how an MHD avalanche might occur in a multi-threaded coronal loop. Considering 23 non-potential magnetic threads within a loop, we use 3D MHD simulations to show that only one thread needs ...
