Rotationally driven quasi‐periodic radio emissions in the Jovian magnetosphere [PDF]
Journal of Geophysical Research: Space Physics, 2006 The occurrence characteristics of Jovian multiple quasi‐periodic (QP) bursts are investigated based on Galileo spacecraft observations. Multiple QP bursts recurrently appeared in a group with a planetary spin period of 10 hours. Their appearance was synchronized with the planetary rotation, i.e., they were preferably excited when Jupiter had a ...

Kinetic Structure of an Interplanetary Shock Observed at Two Heliocentric Longitudes
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Collisionless shocks convert bulk flow energy into heat, electromagnetic fields, and non‐thermal particle populations. Recent studies suggest that downstream magnetic oscillations could play an important role in ion‐scale energy dissipation at low‐Mach‐number shocks; however, the specific shock and plasma parameters involved remain poorly ...

Saturation of Ionospheric Currents under Extreme Environments
The Astrophysical JournalStrong solar wind conditions can drive large electric potentials across planetary polar caps, but previous studies have shown that the cross polar cap potential reaches a saturation point during periods of high interplanetary magnetic field (IMF ...

First Observation of Banded Electron Cyclotron Harmonic Waves at Earth's Magnetopause
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract This letter presents the first observation of banded Electron Cyclotron Harmonic (ECH) waves by Magnetospheric Multiscale (MMS) satellites near the Earth's subsolar magnetopause. The observation shows the fundamental mode (n=1 $n=1$) and its higher harmonics (n=2 $n=2$–6), each with distinct lower and upper bands separated by a spectral gap at

AGU Advances, Volume 7, Issue 1, February 2026.Abstract Energetic electron precipitation plays a pivotal role in shaping Earth's radiation belt dynamics and drives significant physical and chemical changes in the upper atmosphere. However, the detailed mechanisms governing the loss of relativistic electrons have remained unclear, largely due to the limited energy coverage and coarse resolution of ...

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.
