The Dynamic Coupling of Streamers and Pseudostreamers to the Heliosphere
V. Aslanyan, D. I. Pontin, A. K. Higginson +3
The slow solar wind is generally believed to result from the interaction of open and closed coronal magnetic flux at streamers and pseudostreamers. We use 3-dimensional magnetohydr…
The structure of current layers and degree of field line braiding in coronal loops
D. I. Pontin, G. Hornig
One proposed resolution to the long-standing problem of solar coronal heating involves the buildup of magnetic energy in the corona due to turbulent motions at the photosphere that…
Dynamic Topology and Flux Rope Evolution During Non-linear Tearing of 3D Null Point Current Sheets
P. F. Wyper, D. I Pontin
In this work the dynamic magnetic field within a tearing-unstable three-dimensional (3D) current sheet about a magnetic null point is described in detail. We focus on the evolution…
Non-linear Tearing of 3D Null Point Current Sheets
P. F. Wyper, D. I Pontin
The manner in which the rate of magnetic reconnection scales with the Lundquist number in realistic three-dimensional (3D) geometries is still an unsolved problem. It has been demo…
Mimetic Methods for Lagrangian Relaxation of Magnetic Fields
Simon Candelaresi, David Pontin, Gunnar Hornig
We present a new code that performs a relaxation of a magnetic field towards a force-free state (Beltrami field) using a Lagrangian numerical scheme. Beltrami fields are of interes…
