3D WKB solution for fast magnetoacoustic wave behaviour around an X-line
J. A. McLaughlin, G. J. J. Botha, S. Regnier +1
We study the propagation of a fast magnetoacoustic wave in a 3D magnetic field created from two magnetic dipoles. The magnetic topology contains an X-line. We aim to contribute to…
The behaviour of magnetoacoustic waves in the neighbourhood of a two-dimensional null point: initially cylindrically-symmetric perturbations
J. A. McLaughlin
The propagation of magnetoacoustic waves in the neighbourhood of a 2D null point is investigated for both and plasmas. Previous work has shown that the Alfvén speed…
Phase Mixing of Alfvén Waves Near a 2D Magnetic Null Point
J. A. McLaughlin
The propagation of linear Alfvén wave pulses in an inhomogeneous plasma near a 2D coronal null point is investigated. When a uniform plasma density is considered, it is seen that a…
3D Alfven wave behaviour around proper and improper magnetic null points
J. O. Thurgood, J. A. McLaughlin
Context: MHD waves and magnetic null points are both prevalent in many astrophysical plasmas, including the solar atmosphere. Interaction between waves and null points has been imp…
Nonlinear Alfvén wave dynamics at a 2D magnetic null point: ponderomotive force
J. O. Thurgood, J. A. McLaughlin
Context : In the linear, β=0 MHD regime, the transient properties of MHD waves in the vicinity of 2D null points are well known. The waves are decoupled and accumulate at predictab…
Linear and nonlinear MHD mode coupling of the fast magnetoacoustic wave about a 3D magnetic null point
J. O. Thurgood, J. A. McLaughlin
Context: Coronal magnetic null points have been implicated as possible locations for localised heating events in 2D models. We investigate this possibility about fully 3D null poin…
