DOI: 10.1007/s11207-019-1544-1
Abstract: The Hall effect due to weak ionization in the lower solar atmosphere is shown to produce significant coupling between slow magneto-acoustic and Alfven waves, especially in highly inclined magnetic fields, and even at low frequencies… read more here.

DOI: 10.1007/s11207-020-01726-9
Abstract: The self-interaction of the Alfven wave associated with the parametric interaction between the Alfven wave and longitudinal plasma motion induced by this Alfven wave is investigated in a dissipative plasma with a thermal misbalance. The… read more here.

DOI: 10.1038/s41467-019-08551-0
Abstract: Speed of sound waves in gases and liquids are governed by the compressibility of the medium. There exists another type of non-dispersive wave where the wave speed depends on stress instead of elasticity of the… read more here.

DOI: 10.1063/1.5093395
Abstract: Dispersion and damping of kinetic Alfven waves (KAWs) and inertial Alfven waves (IAWs) are studied for the electron-ion Cairns distributed plasmas in the framework of kinetic theory. The phase velocities and damping rates of KAWs… read more here.

DOI: 10.1093/mnras/stab179
Abstract: We argue that charged dust grains could significantly impact the confinement and transport of galactic cosmic rays. For sub-GeV to ~1000GeV cosmic rays, small-scale parallel Alfven waves, which isotropize cosmic rays through gyro-resonant interactions, are… read more here.
