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.

Non-WKB Models of the FIP Effect: The Role of Slow Mode Waves

, 2011
A model for element abundance fractionation between the solar chromosphere and corona is further developed. The ponderomotive force due to Alfven waves propagating through, or reflecting from the chromosphere in solar conditions generally accelerates ...

Solar wind models with Alfven waves

The Astrophysical Journal, 1978
Solutions to the one-fluid solar-wind equations that include pressure and heating due to outwardly propagating Alfven waves are presented. The solutions are given for two forms of the heat flux: the classical Spitzer (1962) formula and a 'collisional' heat flux. Both high-speed and low-speed solar-wind streams are considered.

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 ...

Interactions of oblique interplanetary discontinuities and their manifestations during STIP intervals 15-19 [PDF]

The generation of slow shock waves as the result of the interaction of Alfven discontinuities with solar wind contact surfaces is considered. The latter are taken to be the boundaries of proton and alpha-particle concentration inhomogeneities.

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.

Neutron starquakes and the nature of gamma-ray bursts [PDF]

The possibility that gamma-ray bursts originate from quakes deep in the solid crust of a neutron star is investigated. Seismic waves are radiated if shear stress is relieved by brittle fracture.
