Fast magneto-acoustic waves in the solar chromosphere: Comparison of single-fluid and two-fluid approximations

M. M. Gómez Míguez, D. Martínez-Gómez, E. Khomenko +3

Context: The mechanism behind the heating of the solar chromosphere remains unclear. Friction between neutrals and charges is expected to contribute to plasma heating in a partiall…

MHD waves in homogeneous and continuously stratified atmospheres

Paul S. Cally, Thomas J. Bogdan

The basic equations, concepts, and modes of linear, ideal, MHD waves -- slow, Alfvén and fast -- are set out and generalised to gravitationally-stratified atmospheres. Particular a…

Efficiency of MHD Wave Generation in Weakly Ionized Atmospheres

Paul S. Cally

Generation of Alfvén and slow magneto-acoustic waves in weakly ionized atmospheres by excitation of the charges-only component of the two fluid (charges and neutrals) plasma is sho…

Wave Conversion, Decay and Heating in a Partially Ionized Two-Fluid Magneto-Atmosphere

Paul S Cally, M. M. Gomez-Miguez

A ray-theoretic phase space description of linear waves in a two-fluid (charges and neutrals) magnetized plasma is used to calculate analytic decay rates and mode transmission and…

On the Fragility of Alfvén waves in a Stratified Atmosphere

Paul S. Cally

Complete asymptotic expansions are developed for slow, Alfvén and fast magnetohydrodynamic waves at the base of an isothermal three-dimensional (3D) plane stratified atmosphere. To…

Benchmarking Hall-Induced Magnetoacoustic to Alfvén Mode Conversion in the Solar Chromosphere

Abbas Raboonik, Paul Cally

A 2.5D numerical model of magnetoacoustic-Alfvén linear mode conversions in the partially ionised low solar atmosphere induced by the Hall effect is surveyed, varying magnetic fiel…
