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 ...

Toward 3D MHD modeling of neoclassical tearing mode suppression by ECCD
We propose a framework to extend the magnetohydrodynamic (MHD) equations to include electron cyclotron current drive (ECCD) and discuss previous models proposed by Giruzzi et al. [2] and by Hegna and Callen [3].

Effect of nanoparticle shape on unsteady liquid film flow of MHD Oldroyd-B ferrofluid
A computational framework is carried out to investigate the drive, and thermal transport of the thin-film flow of unstable magnetohydrodynamic (MHD) Oldroyd-B ferrofluid suspend with cobalt ferrite (CoFe2O4) nanoparticles in water.

Unveiling the Mechanism for the Rapid Acceleration Phase in a Solar Eruption
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 ...

Magnetohydrodynamic Turbulence Formation in Solar Flares: 3D Simulation and Synthetic Observations
Turbulent plasma motion is common in the universe and invoked in solar flares to drive effective acceleration leading to high-energy electrons. Unresolved mass motions are frequently detected in flares from extreme ultraviolet (EUV) observations, which ...
