Comments on "Plasma current drive by injection of photons with helicity" [Comm. Plasma Phys. Controlled Fusion 12, 165 (1989)] [PDF]
, 1989 Ohkawa has proposed a tokamak current-drive scheme [Comm. Plasma Phys. Controlled Fusion 12, 165 (1989)], which relies on the injection of circularly polarized magnetohydrodynamic waves.

Can useful toroidal current be driven by classical viscoresistive Alfvén waves? [PDF]
, 1991 Simple, yet exact, analytic solutions for the shear and compressional Alfvén wave are obtained for helical magnetohydrodynamic (MHD) waves in cylindrical geometry with both resistivity and viscosity included.

Space Weather, 2021 Previously, Tsurutani and Lakhina (2014, https://doi.org/10.1002/2013GL058825) created estimates for a “perfect” interplanetary coronal mass ejection and performed simple calculations for the response of geospace, including dB/dt.

How Transverse Waves Drive Turbulence in the Solar Corona
Symmetry, 2022 Oscillatory power is pervasive throughout the solar corona, and magnetohydrodynamic (MHD) waves may carry a significant energy flux throughout the Sun’s atmosphere.

Toward 3D MHD modeling of neoclassical tearing mode suppression by ECCD
EPJ Web of Conferences, 2012 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].

High-order coupling of shear and sonic continua in JET plasmas
Nuclear Fusion, 2023 A recent model coupling the shear-Alfvén and acoustic continua, which depends strongly on the equilibrium shaping and on elongation in particular, is employed to explain the properties of Alfvénic activity observed on JET plasmas below but close to the ...

Tidally driven dynamos in a rotating sphere [PDF]
, 2014 Large-scale planetary or stellar magnetic fields generated by a dynamo effect are mostly attributed to flows forced by buoyancy forces in electrically conducting fluid layers.

Reconnection Studies Under Different Types of Turbulence Driving [PDF]
, 2012 We study a model of fast magnetic reconnection in the presence of weak turbulence proposed by Lazarian and Vishniac (1999) using three-dimensional direct numerical simulations. The model has been already successfully tested in Kowal et al.

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.
