Plasmaspheric High‐Frequency Whistlers as a Candidate Cause of Shock Aurora at Earth
Geophysical Research Letters, 2023 Auroral brightening driven by interplanetary shocks on Earth's closed magnetic field lines is commonly attributed to the 0.1–10 keV electron precipitations by electron cyclotron harmonic waves and whistler‐mode chorus waves in the low‐density region.

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract Venus‐ward return flow can significantly influence ion escape from Venus and may therefore play an important role in atmospheric evolution. However, the mechanism driving return flow remains under debate. Here, we investigate the occurrence rate and spatial distribution of ion return flows in the Venusian induced magnetotail, and their ...

Interpretation of Flat Energy Spectra Upstream of Fast Interplanetary Shocks
The Astrophysical Journal, 2023 Interplanetary shocks are large-scale heliospheric structures often caused by eruptive phenomena at the Sun, and represent one of the main sources of energetic particles.

Plasma and Electric Environment Within Lunar Pits and Caves Exposed to the Solar Wind
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract We have assessed the plasma and electric environment within a lunar pit and its connected subsurface cave utilizing plasma simulations. It is shown that adjacent illuminated and shadowed regions along the interior walls of the pit induce differential charging, exceeding the levels typically observed on open planar surfaces.

On the Formation of Super-Alfvénic Flows Downstream of Collisionless Shocks
The Astrophysical JournalSuper-Alfvénic jets, with kinetic energy densities significantly exceeding that of the solar wind, are commonly generated downstream of Earth's bow shock under both high- and low-beta plasma conditions. In this study, we present theoretical evidence that

AGU Advances, Volume 7, Issue 8, November 2026.Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.

The Astrophysical JournalHeliospheric suprathermal ions include inner-source pickup ions, cometary ions, solar energetic particles, and suprathermal tail particles. Despite exhaustive observation and formalisms, their role in interplanetary shock acceleration has yet to be ...

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence
Earth and Space Science, Volume 13, Issue 11, November 2026.Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

Turbulence and Polytropic Changes across Interplanetary Shocks Observed by the Parker Solar Probe
The Astrophysical Journal LettersInterplanetary shocks play a critical role in solar wind dynamics, influencing the properties of turbulence and thermodynamic processes. In this study, we statistically analyze changes in turbulence characteristics and polytropic indices across 37 quasi ...
