Cool Stars and Space Weather

, 2014
Stellar flares, winds and coronal mass ejections form the space weather. They are signatures of the magnetic activity of cool stars and, since activity varies with age, mass and rotation, the space weather that extra-solar planets experience can be very ...

Double Layers in the Martian Magnetosheath

The Astrophysical Journal
The observation of electrostatic double layers in Martian magnetosheath plasma is reported, based on medium-frequency (100 Hz–32 kHz) electric field data recorded by the Langmuir Probe and Waves on board the Mars Atmosphere and Volatile Evolution ...

Ion Cyclotron Waves Associated With Ionospheric Outflow at Jupiter

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The mechanism driving ion outflow from Jupiter's auroras remains to be determined. H+ ${\mathrm{H}}^{+}$ outflow has been observed with highly field‐aligned pitch angles consistent with acceleration by high‐altitude electrostatic potential structures.

Ultralow-frequency Waves in Jupiter’s Magnetopause Boundary Layer

The Astrophysical Journal
Ultralow-frequency (ULF) waves (∼tens of minutes period) are widely identified in the Jovian system and are believed to be associated with energy dissipation in the magnetosphere and ionosphere.

The Role of Planetary Rotation in Polar Cusp Localization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Juno observations have revealed that Jupiter's polar cusps are displaced toward dusk and even the nightside, contradicting the Earth‐derived paradigm that is confined to narrower ranges near noon. These findings underscore the overlooked influence of planetary rotation on magnetospheric dynamics, exposing a critical gap in current theoretical ...

Electron Dispersion at the Electron Edge of the Earth's Magnetospheric Cusp

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission observes electron energy‐latitude dispersion at the equatorward edge of the magnetospheric cusp, and high‐cadence Analyzer for Cusp Electrons (ACE) measurements resolve the dispersed edge. The inverse velocity dispersion (low energy before high energy)

Small-scale Field-aligned Currents in the Magnetopause Boundary Layer

The Astrophysical Journal
Based on high-resolution measurements from the Magnetospheric Multiscale mission from 2015 May to 2018 June, we statistically investigate the properties of small-scale field-aligned currents (SFACs) in the magnetopause boundary layer.

Magnetic Rope Is an Electron Selector: Discovery in Space and Conceptual Application to Medicine

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Magnetic rope is a helical structure existing ubiquitously in astrophysical and space plasmas. Such structure has been conventionally known to accelerate electrons, convert energy, and play key roles in driving solar eruptions. Here, in contrast to the conventional concept, we report that the magnetic rope can divert electrons efficiently in ...

Backscattering of Ions Impacting Ganymede’s Surface as a Source for Energetic Neutral Atoms

The Astrophysical Journal Letters
Jupiter’s largest moon Ganymede has its own intrinsic magnetic field, which forms a magnetosphere that is embedded within Jupiter’s corotating magnetospheric plasma.
