Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Ultra‐low‐frequency (ULF) waves cause local Thermosphere‐Ionosphere (T‐I) perturbations, but their impacts on the global T‐I system including the generation of Traveling Atmospheric Disturbances (TADs) have never been evaluated. The mechanisms responsible for the TAD generation and propagation, whether through dynamic or thermal process, are ...

Poloidal Field Line Resonances Driven by a Fast Wave
Geophysical Research LettersWe present numerical simulations of the excitation of resonant poloidal Alfvén waves. The resulting Alfvén waves could be loosely described as “high‐m” (m is the azimuthal wave number) in as much as the azimuthal scale of the wave is much less than the ...

Europa is Embedded in Non‐Maxwellian, Anisotropic Electron Distributions
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract In September 2022, the Juno spacecraft flew by Europa, providing new insight into the electron pitch angle and energy distributions via the Jovian Auroral Distributions Experiment electron analyzers (JADE‐E). We fit these observations with two anisotropic kappa distributions (cold and hot), accounting for spacecraft potential, which we find to

Prevalence of Small-scale Jets from the Networks of the Solar Transition Region and Chromosphere
, 2014 As the interface between the Sun's photosphere and corona, the chromosphere and transition region play a key role in the formation and acceleration of the solar wind.

Short‐Term Variability of Jupiter's Satellite Footprints as Spotted by JWST
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract We present the main Alfvén wing (MAW) spots of Io and Europa as observed by the Near‐Infrared Spectrograph onboard the James Webb Space Telescope. These auroral footprint features have been measured previously, but only in emission. Here, the derived ionospheric H3+ ${\mathrm{H}}_{3}^{+}$ emission, temperature and column density are reported ...

The Energy Content of Alfvén Waves in the Stratified Solar Atmosphere
The Astrophysical JournalAlfvén waves propagating in a vertically stratified plasma, such as those traveling from the solar photosphere to the corona, are partially reflected due to the gradient in the Alfvén speed.

Transverse waves in coronal flux tubes with thick boundaries: The effect of longitudinal flows
, 2019 Observations show that transverse magnetohydrodynamic (MHD) waves and flows are often simultaneously present in magnetic loops of the solar corona.

On the Correlation between Alfvén Waves and Auroral Radio Emissions in the Jovian System
The Astrophysical JournalJupiter’s powerful aurorae reflect intense energy dissipation in the magnetosphere–ionosphere system. Recent studies reveal that solar wind compression systematically enhances auroral emission, while the mechanism is not yet fully understood.
