    • Three dimensional MHD simulations of the dynamics and energetics of coronal flux tubes 

      Howson, Thomas Alexander (University of St Andrews, 2019-06-25) - Thesis
      In this thesis we present the results of three-dimensional MHD simulations of the evolution of magnetic flux tubes within the solar atmosphere. We consider the dynamics and energetics of coronal loops that are perturbed ...

    • Numerical modelling of ultra low frequency waves in Earth's magnetosphere 

      Elsden, Tom (University of St Andrews, 2016-06-24) - Thesis
      Ultra Low Frequency (ULF) waves are a ubiquitous feature of Earth's outer atmosphere, known as the magnetosphere, having been observed on the ground for almost two centuries, and in space over the last 50 years. These waves ...

    • Eruptions and jets in the Sun 

      Lee, Eon Jui (University of St Andrews, 2017-06-23) - Thesis
      Magnetic flux emergence is a fundamental process in the Sun, during which magnetic fields emerge from the solar interior to the surface, to build up active regions and give onset to spectacular dynamic phenomena, such as ...

    • The dynamic topology of the solar corona : mapping the Sun’s three dimensional magnetic skeleton 

      Williams, Benjamin Matthew (University of St Andrews, 2018-06-26) - Thesis
      Observations of the surface of the Sun reveal multi-scaled, mixed magnetic features that carpet the entire solar surface. Not surprisingly, the global magnetic fields extrapolated from these observations are highly ...

    • Modelling chromospheric evaporation in response to coronal heating 

      Johnston, Craig David (University of St Andrews, 2018-06-26) - Thesis
      This thesis presents a new computationally efficient method for modelling the response of the solar corona to the release of energy. During impulsive heating events, the coronal temperature increases which leads to a ...
