Modeling the Detectability of Energetic Heliospheric Ions at Pluto During the New Horizons Flyby

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We investigate the detectability of heliospheric helium ions at energies up to 100 keV by the New Horizons (NH) spacecraft during its flyby through Pluto's induced magnetosphere. The Pluto Energetic Particle Spectrometer Science Investigation energetic ion detector observed a reduction in their flux by an order of magnitude as the spacecraft ...

The Incompressible Magnetohydrodynamic Energy Cascade Rate Upstream of Mars: Effects of the Total Energy and the Cross-helicity on Solar Wind Turbulence

The Astrophysical Journal
Solar wind turbulence is a dynamical phenomenon that evolves with heliocentric distance. Orbiting Mars since 2014 September, Mars Atmosphere and Volatile EvolutioN offers a unique opportunity to explore some of its main properties beyond ∼1.38 au.

Simultaneous Compressive Kinetic‐Scale Fluctuations and Second‐Harmonic Proton Cyclotron Waves Inside a Martian Magnetosheath Structure

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mars directly interacts with the solar wind and hosts a complex plasma‐wave environment. Using MAVEN observations, we identify an event in the dusk‐side Martian magnetosheath where strongly compressive sub‐cyclotron kinetic‐scale fluctuations coexist with second‐harmonic proton cyclotron waves (PCWs).

Observations of High‐Resolution Two‐Dimensional Ionospheric Flow Dynamics Associated With Poleward Boundary Intensifications

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Poleward boundary intensifications (PBIs) are one of the most common auroral disturbances and have been shown to play a key role in substorm dynamics. PBIs are commonly interpreted as the ionospheric signature of magnetotail reconnection, providing insight into X‐line evolution.

Interaction between Winds from Weak-lined T Tauri Stars with Exoplanetary Magnetospheres

The Astrophysical Journal
T Tauri stars, in more advanced stages of evolution, during the final accretion phase of stellar formation, exhibit intense stellar winds and surface magnetic fields with intensities around a kilogauss.

Observation of Turbulent Magnetohydrodynamic Cascade in the Jovian Magnetosheath

The Astrophysical Journal, 2023
We present the first estimation of the energy cascade rate in Jupiter’s magnetosheath (MS). We use in situ observations from the Jovian Auroral Distributions Experiment and the magnetometer investigation instruments on board the Juno spacecraft, in ...

Precessing planetary magnetospheres in SiO stars? [PDF]

Astronomy & Astrophysics, 2009
Context. The origin of magnetism around asymptotic giant branch (AGB) stars remains an uncertainty. These stars may drive an important dynamo, but if the magnetic energy dissipates entirely into X-rays, the observed X-ray luminosities are too low to maintain a strong, dynamically important global field.

Influence of the Eccentric Geomagnetic Dipole on Longitude Variations of Compressional Upstream Wave Amplitudes in the Topside Ionosphere: Results From the MSS‐1A Satellite

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Based on 2‐year magnetic data from the Macau science satellite, we investigate the compressional Pc3‐4 pulsations (between 16 and 100 mHz) driven by upstream waves (UWs). Our results confirm larger UWs amplitudes in the South Atlantic Anomaly (SAA) longitudes, agreeing with previous missions.

Electron Energization by Ion Density Enhancement in the Martian Magnetotail—MAVEN Observations

The Astrophysical Journal
It has been long observed at Mars that electron fluxes are enhanced during the tail current sheet crossings, of which the cause is not well understood. We use a novel approach to reveal one of the electron energization mechanisms with observations from ...
