Correlation of High‐Latitude Scintillation With Auroral Precipitation: Case Studies Using GNSS Radio Occultation Data From PlanetiQ

Space Weather, Volume 24, Issue 9, September 2026.
Abstract This study presents a survey of high‐latitude ionospheric scintillation using GNSS radio occultation (RO) data from the PlanetiQ satellite. The analysis examines 483 high‐latitude RO tracks between January and May 2023, with 371 tracks exhibiting scintillation events.

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.

Global Circulation of Martian Ionospheric Currents Revealed by Magnetometer Data

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract In the dynamo region of the Martian ionosphere, a large‐scale current is generated by charge separation: ions collide with neutrals while electrons preferentially gyrate around local magnetic field lines. Using MAVEN magnetometer data and a physics‐informed neural network constrained by Ampère's law and Gauss's law for magnetism (the Neural ...

The case for studying other planetary magnetospheres and atmospheres in Heliophysics [PDF]

, 2023
Heliophysics is the field that "studies the nature of the Sun, and how it influences the very nature of space - and, in turn, the atmospheres of planetary bodies and the technology that exists there." However, NASA's Heliophysics Division tends to limit ...

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 ...

Extreme Radiation Belt Dropout During the May 2024 Superstorm

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract The geomagnetic superstorm in May 2024 represents the most extreme space weather event over the past two decades, offering a unique opportunity to investigate radiation belt electron dynamics under exceptionally strong solar wind driving conditions. Observations from the Arase satellite show that relativistic electron fluxes dropped by several

Sensitivity of the Martian Magnetotail to Model Configuration Choices in Multispecies MHD Simulations

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Numerical modeling has been a key component in the study of the Mars space environment, providing a comprehensive global representation that is not always easy to obtain in spacecraft measurements. However, there are inconsistencies in data‐model and model‐model comparisons, regardless of whether the simulation conditions are identical or ...

Quasi 6‐Day Wave Variability in the Thermosphere and Ionosphere: Observations and Modeling

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of the upper mesosphere and lower thermosphere from TIMED‐SABER and ICON‐MIGHTI reveal a clear Quasi 6‐Day Wave (Q6DW) event in the winds and temperatures in this region. This Q6DW event persists across multiple data sets throughout the middle‐to‐upper thermosphere and the F‐region ionosphere, including GOLD disk ...

Mach Number Scaling of Foreshock Magnetic Fluctuations at Quasi-parallel Bow Shocks and Their Role in Magnetospheric Driving Throughout the Solar System

The Astrophysical Journal
Upstream of quasi-parallel bow shocks, reflected ions generate ion–ion instabilities. The resulting magnetic fluctuations can advect through the shock and interact with planetary magnetospheres.
