Radial Evolution of Turbulence Spectra on the Jovian Magnetosheath Flanks: Juno Observations

The Astrophysical Journal
The Jovian magnetosheath provides a unique environment for examining the radial evolution of magnetosheath turbulence due to its large spatial extent.

Origin of electron cyclotron maser-induced radio emissions at ultra-cool dwarfs: magnetosphere-ionosphere coupling currents

, 2012
A number of ultra-cool dwarfs emit circularly polarised radio waves generated by the electron cyclotron maser instability. In the solar system such radio is emitted from regions of strong auroral magnetic field-aligned currents.

Extra Zebra Stripes Observed by Macao Science Satellite‐1 in the Inner Radiation Belt

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Zebra stripes, characterized by periodic banded structures in the energy‐L shell spectra of energetic electrons in the Earth's inner radiation belt, are understood to result from the azimuthal drift of electrons perturbed by prompt electric field perturbations.

Whistler Chorus Amplification in the Magnetosphere: The Nonlinear Free‐Electron Laser Model and the Ginzburg‐Landau Equation

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We present a novel nonlinear model for whistler‐mode chorus amplification based on the free‐electron laser (FEL) mechanism. First, we derive the nonlinear collective variable equations for the whistler‐electron interaction. Consistent with in situ satellite observations, these equations predict that a small seed wave can undergo exponential ...

Saturn’s Recurrent Auroral Flashes in the Equinoctial Campaign

The Astrophysical Journal
The past decades of Cassini’s investigation around Saturn have revealed the frequent occurrence of ∼1 hr quasiperiodic (QP) signatures in the in situ magnetic field and plasma measurements and plasma wave observations. Saturn’s aurora, as the response to

Energetic particles of the outer regions of planetary magnetospheres [PDF]

High energy particles, with energies above those attainable by adiabatic or steady-state electric field acceleration, have been observed in and around the outer regions of planetary magnetospheres.

Magnetic Field and Plasma Asymmetries Between the Martian Quasi‐Perpendicular and Quasi‐Parallel Magnetosheaths

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The Martian magnetosheath acts as a conduit for mass and energy transfer between the upstream solar wind and its induced magnetosphere. However, our understanding of its global properties remains limited. Using 9 years of data from NASA's Mars Atmosphere and Volatile EvolutioN mission, we performed a quantitative statistical analysis to ...

Statistical Analysis of Multiple Bow Shock Crossings at Mars

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract We conduct a statistical analysis of multiple bow shock (BS) crossings at Mars. Data from the magnetometer (MAG) and Solar Wind Ion Analyzer (SWIA) onboard the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft from its first 2 years in orbit is used to identify flapping events.
