Solar Cycle Variation of the Distribution of Photospheric Magnetic Flux Features
Callan N. Noble, Clare E. Parnell, Thomas Neukirch
We use statistical tools to analyse data from the Solar Dynamics Observatory Helioseismic and Magnetic Imager to determine the distribution of the magnetic flux of photospheric mag…
UK White Paper on Magnetic Reconnection
Alexander J. B. Russell, James A. McLaughlin, Philippa Browning +25
Magnetic reconnection powers explosive releases of magnetic energy, heating and particle acceleration throughout the plasma universe. Knowledge of this universal process is vital t…
MHSXtraPy -- A Python code for the extrapolation of magnetohydrostatic fields on the Sun using analytical solutions
Lilli Nadol, Thomas Neukirch
We present a Python code for calculating and displaying magnetic field extrapolations from given two-dimensional boundary conditions, specifically from solar surface magnetograms.…
Models of Collisionless Quasineutral Solar Wind Current Sheets
Sophie Boswell, Thomas Neukirch, Anton Artemyev +2
In situ measurements of kinetic scale current sheets in the solar wind show that they are often approximately force-free although the plasma beta is of order one. They frequently d…
An efficient method for magnetic field extrapolation based on a family of analytical three-dimensional magnetohydrostatic equilibria
Lilli Nadol, Thomas Neukirch
With current observational methods it is not possible to directly measure the magnetic field in the solar corona with sufficient accuracy. Therefore, coronal magnetic field models…
A detailed investigation of particle energisation mechanisms in models of collapsing magnetic traps
Kate Mowbray, Thomas Neukirch, James Threlfall
In this paper we provide a detailed investigation of the energisation processes in two-dimensional, two and a half-dimensional and three-dimensional collapsing magnetic trap models…
