A Magnetohydrodynamic Boost for Relativistic Jets [PDF]
, 2007 We performed relativistic magnetohydrodynamic simulations of the hydrodynamic boosting mechanism for relativistic jets explored by Aloy & Rezzolla (2006) using the RAISHIN code.

The Astrophysical Journal, 2023 The angular momentum of gas feeding a black hole (BH) may be misaligned with respect to the BH spin, resulting in a tilted accretion disk. Rotation of the BH drags the surrounding spacetime, manifesting as Lense–Thirring torques that lead to disk ...

A reduced magnetohydrodynamic model of coronal heating in open magnetic regions driven by reflected low-frequency waves [PDF]
, 2001 A reduced magnetohydrodynamic (RMHD) description is employed to examine a suggestion made by W. H. Matthaeus and colleagues in 1999 that coronal heating might be sustained by a cascade of low-frequency MHD turbulence.

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

Global Alfven Wave Heating of the Magnetosphere of Young Stars [PDF]
, 2002 Excitation of a Global Alfven wave (GAW) is proposed as a viable mechanism to explain plasma heating in the magnetosphere of young stars. The wave and basic plasma parameters are compatible with the requirement that the dissipation length of GAWs be ...

Magnetohydrodynamic turbulence in warped accretion discs [PDF]
, 2001 Warped, precessing accretion discs appear in a range of astrophysical systems, for instance the X-ray binary Her X-1 and in the active nucleus of NGC4258.

Unveiling the Mechanism for the Rapid Acceleration Phase in a Solar Eruption
The Astrophysical Journal Letters, 2023 Two major mechanisms have been proposed to drive the solar eruptions: the ideal magnetohydrodynamic instability and the resistive magnetic reconnection. Due to the close coupling and synchronicity of the two mechanisms, it is difficult to identify their ...
