Investigating the Role of Inward Alfvén Waves and Structures in the Slow Solar Wind

The Astrophysical Journal
The solar wind dynamics are thought to be governed by counter-propagating Alfvén waves. Alfvén waves generate a turbulent cascade through nonlinear couplings between shearing wave packets. However, imbalances, structures, and intermittency complicate the

Distribution of equatorial Alfvén velocity in the magnetosphere: a statistical analysis of THEMIS observations

Earth, Planets and Space, 2018
It has been known that the Alfvén velocity plays a significant role in generation and propagation of magnetohydrodynamic (MHD) waves. Until now, however, the global distribution of the Alfvén velocity in the magnetosphere has not been reported.

Solitary Alfvén Waves

The Astrophysical Journal Letters
We present the solitary Alfvén wave as an ideal nonlinear Alfvénic solution in the solitary far-field limit and construct a 3D numerical model—an Alfvénon.

Modeling the Effects of a Light Bridge on Properties of Magnetohydrodynamic Waves in Solar Pores

The Astrophysical Journal
Solar pores are ideal magnetic structures for wave propagation and transport of energy radially outwards across the upper layers of the solar atmosphere.

MHD WAVES IN THE COLLISIONAL PLASMA OF THE SOLAR CORONA AND TERRESTRIAL IONOSPHERE

Solar-Terrestrial Physics, 2020
We have studied MHD waves (Alfvén and fast compressional modes) in a homogeneous collisional three-component low-β plasma. The three-component plasma consists of electrons, ions, and neutrals with arbitrary ratio between collision frequencies and wave ...

One-dimensional Linear Analysis and Numerical Simulations of Alfvén Waves in a Force-free Magnetosphere around a Kerr Black Hole

The Astrophysical Journal
We perform 1D linear analysis and numerical simulations of the propagation of Alfvén waves in a force-free magnetosphere along magnetic field lines around a spinning black hole.
