Spatial Scales and Locality of Magnetic Helicity: Part 1
Christopher Prior, Gareth Hawkes, Mitch Berger
Magnetic helicity is approximately conserved in resistive MHD models. It quantifies the entanglement of the magnetic field within the plasma. The transport and removal of helicity…
The Evolution of Writhe in Kink-Unstable Flux Ropes and Erupting Filaments
Tibor Torok, Bernhard Kliem, Mitchell A. Berger +3
The helical kink instability of a twisted magnetic flux tube has been suggested as a trigger mechanism for solar filament eruptions and coronal mass ejections (CMEs). In order to i…
The Build-up to Eruptive Solar Events Viewed as the Development of Chiral Systems
Sara F. Martin, Olga Panasenco, Mitchell A. Berger +4
When we examine the chirality or observed handedness of the chromospheric and coronal structures involved in the long-term build-up to eruptive events, we find that they evolve in…
The flow of forces through cellular materials
Mitchell A. Berger
Describing and measuring the elastic properties of cellular materials such as honeycombs and foams can be a difficult problem when the cell structure is disordered. This paper sugg…
The evaluation of directionally writhing polymers
C B Prior, M A Berger
We discuss the appropriate techniques for modelling the geometry of open ended elastic polymer molecules. The molecule is assumed to have fixed endpoints on a boundary surface. In…
The writhe of helical structures in the solar corona
Tibor Toeroek, Mitchell A. Berger, Bernhard Kliem
Helicity is a fundamental property of magnetic fields, conserved in ideal MHD. In flux rope topology, it consists of twist and writhe helicity. Despite the common occurrence of hel…
