Phantom: A smoothed particle hydrodynamics and magnetohydrodynamics code for astrophysics [PDF]

open access: yes, 2017
We present Phantom, a fast, parallel, modular and low-memory smoothed particle hydrodynamics and magnetohydrodynamics code developed over the last decade for astrophysical applications in three dimensions. The code has been developed with a focus on stellar, galactic, planetary and high energy astrophysics and has already been used widely for studies ...

Laboratory observation of a nonlinear interaction between shear Alfv\'{e}n waves

open access: yes, 2005
An experimental investigation of nonlinear interactions between shear Alfv\'{e}n waves in a laboratory plasma is presented. Two Alfv\'{e}n waves, generated by a resonant cavity, are observed to beat together, driving a low frequency nonlinear psuedo-mode

Evolution of Force‐Free Magnetic Structure in the Dayside Ionosphere of Mars

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Magnetic fields measured in the ionosphere of Mars by the magnetometers onboard the Mars Atmosphere and Volatile EvolutioN (MAVEN) and the Mars Global Surveyor (MGS) spacecraft display a wide range of spatial scales, ranging from global to small‐scale.

Multispecies MHD Simulations of the Crustal Field Influence at the Mars Magnetotail Current Sheet

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract The magnetotail current sheet of Mars exhibits a dawn‐to‐dusk asymmetry that has been seen in satellite observations and MHD simulations. However, the influence of season has not been thoroughly investigated in MHD simulations. This investigation incorporates seasonal variations, driven by planetary eccentricity and solar variability, within ...

Review of Conductive Reciprocating Liquid Metal Magnetohydrodynamic Generators

open access: yesEnergies
Reciprocating liquid metal magnetohydrodynamic (MHD) power generation is a new MHD power generation method in which the working fluid is a single-phase liquid metal with a low melting point and high conductivity.

Magnetic Effects at the Edge of the Solar System: MHD Instabilities, the de Laval nozzle Effect and an Extended Jet

open access: yes, 2004
To model the interaction between the solar wind and the interstellar wind, magnetic fields must be included. Recently Opher et al. 2003 found that, by including the solar magnetic field in a 3D high resolution simulation using the University of Michigan ...

The Magnetic Topology of AR13664 Leading to Its First Halo CME

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract In the first half of May 2024, the solar active region (AR) NOAA 13664 was responsible for generating the strongest geomagnetic storm in over 20 years through an enhanced production of coronal mass ejections (CMEs). A key factor in this production was the complex magnetic topology of AR13664.

Numerical simulations of imbalanced strong magnetohydrodynamic turbulence

open access: yes, 2009
Magnetohydrodynamics (MHD) is invoked to address turbulent fluctuations in a variety of astrophysical systems. MHD turbulence in nature is often anisotropic and imbalanced, in that Alfvenic fluctuations moving in opposite directions along the background ...

Computation of inverse magnetic cascades [PDF]

open access: yes, 1981
Inverse cascades of magnetic quantities for turbulent incompressible magnetohydrodynamics are reviewed, for two and three dimensions. The theory is extended to the Strauss equations, a description intermediate between two and three dimensions appropriate
