Dependence of Coronal Loop Heating on the Characteristics of Slow Photospheric Motions
M. L. Ritchie, A. L. Wilmot-Smith, G. Hornig
The Parker hypothesis (Parker (1972)) assumes that heating of coronal loops occurs due to reconnection, induced when photospheric motions braid field lines to the point of current…
Evolution of field line helicity during magnetic reconnection
Alexander J. B. Russell, Anthony R. Yeates, Gunnar Hornig +1
We investigate the evolution of field line helicity for magnetic fields that connect two boundaries without null points, with emphasis on localized finite-B magnetic reconnection.…
An overview of flux braiding experiments
A. L. Wilmot-Smith
Parker has hypothesised that, in a perfectly ideal environment, complex photospheric motions acting on a continuous magnetic field will result in the formation of tangential discon…
Heating of braided coronal loops
A. L. Wilmot-Smith, D. I. Pontin, A. R. Yeates +1
We investigate the relaxation of braided magnetic loops in order to find out how the type of braiding via footpoint motions affects resultant heating of the loop. Two magnetic loop…
A time-dependent model for magnetic reconnection in the presence of a separator
A. L. Wilmot-Smith, G. Hornig
We present a model for separator reconnection due to an isolated reconnection process. Separator reconnection is a process which occurs in the neighbourhood of a distinguished fiel…
Topological Constraints on Magnetic Relaxation
A. R. Yeates, G. Hornig, A. L. Wilmot-Smith
The final state of turbulent magnetic relaxation in a reversed field pinch is well explained by Taylor's hypothesis. However, recent resistive-magnetohydrodynamic simulations of th…
Dynamics of braided coronal loops II: Cascade to multiple small-scale reconnection events
D. I. Pontin, A. L. Wilmot-Smith, G. Hornig +1
Aims: Our aim is to investigate the resistive relaxation of a magnetic loop that contains braided magnetic flux but no net current or helicity. The loop is subject to line-tied bou…
Dynamics of braided coronal loops - I. Onset of magnetic reconnection
A. L. Wilmot-Smith, D. I. Pontin, G. Hornig
The response of the solar coronal magnetic field to small-scale photospheric boundary motions including the possible formation of current sheets via the Parker scenario is one of o…
Magnetic Braiding and Quasi-Separatrix Layers
A. L. Wilmot-Smith, G. Hornig, D. I. Pontin
The squashing factor Q (Titov et al. 2002), a property of the magnetic field line mapping, has been suggested as an indicator for the formation of current sheets, and subsequently…
Lagrangian relaxation schemes for calculating force-free magnetic fields, and their limitations
D. I. Pontin, G. Hornig, A. L. Wilmot-Smith +1
Force-free magnetic fields are important in many astrophysical settings. Determining the properties of such force-free fields -- especially smoothness and stability properties -- i…
Magnetic Braiding and Parallel Electric Fields
A. L. Wilmot-Smith, G. Hornig, D. I. Pontin
The braiding of the solar coronal magnetic field via photospheric motions - with subsequent relaxation and magnetic reconnection -- is one of the most widely debated ideas of solar…
