Influence of Resonant Absorption on the Generation of the Kelvin-Helmholtz Instability

Frontiers in Physics, 2019
The inhomogeneous solar corona is continuously disturbed by transverse MHD waves. In the inhomogeneous environment of coronal flux tubes, these waves are subject to resonant absorption, a physical mechanism of mode conversion in which the wave energy is ...

Effect of partial ionization on wave propagation in solar magnetic flux tubes [PDF]

, 2013
Observations show that waves are ubiquitous in the solar atmosphere and may play an important role for plasma heating. The study of waves in the solar corona is usually based on linear ideal magnetohydrodynamics (MHD) for a fully ionized plasma. However,

Asymmetrically Distributed Kelvin‐Helmholtz Instability at Venusian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The asymmetric distribution of Kelvin‐Helmholtz (KH) instability at Venusian ionopause is investigated using a multifluid model. Results show that KH instability distributes asymmetrically, preferentially developing in the −E (anti‐parallel to the interplanetary electric field) hemisphere.

Effects of MHD slow shocks propagating along magnetic flux tubes in a dipole magnetic field [PDF]

Nonlinear Processes in Geophysics, 2002
Variations of the plasma pressure in a magnetic flux tube can produce MHD waves evolving into shocks. In the case of a low plasma beta, plasma pressure pulses in the magnetic flux tube generate MHD slow shocks propagating along the tube.

Mars' Ionospheric Response to the Onset and Early Phase of 20 May 2024 Solar Flare

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar extreme ultraviolet (EUV, 10–100 nm) and X‐ray (<10 nm) photons are the primary ionization source for the dayside Mars ionosphere. Their fluxes, especially at short wavelengths, increase significantly during solar flares. Among the series of solar flares and solar storms encountered by Earth and Mars in May 2024, one of the strongest ...

Science‐Towards‐Technology Breakthrough in CO2 Electroreduction: Multiphysics, Multiscale, and Artificial Intelligence Insights

Advanced Materials, Volume 38, Issue 22, 17 April 2026.
Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Recent advances in boosting interfacial bubble dynamics with external fields

Droplet, Volume 5, Issue 2, April 2026.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

Alfvén Wave Heating of Solar Chromosphere Reexamined

The Astrophysical Journal
Models of heating the weakly ionized solar atmosphere by collisional damping of upward-propagating Alfvén waves, calculated under the assumption that only incompressible (intermediate-mode) MHD waves are involved, have predicted heating rates that do not
