Polytropic Index and Thermodynamic Behavior of the Central Plasma Sheet Near Lunar Distances

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract In addition to making near‐Earth observations, the THEMIS/ARTEMIS mission is uniquely positioned at lunar distance, in the deep magnetotail, reaching distances of 60 RE ${R}_{E}$ and further. This vantage point allows ARTEMIS to access the plasma sheet and measure entropy evolution across convective channels, plasma flow gradients ...

Mars' O+ ${\mathbf{O}}^{+}$ and O2+ ${\mathbf{O}}_{\mathbf{2}}^{+}$ Ion Escape During Disappearing Solar Wind Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Disappearing solar wind events (DSWEs), intervals when the solar wind proton density <1 cm−3 ${\text{cm}}^{-3}$, represent one extreme of the Mars solar wind interaction. Using data from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission from February 2016 to May 2024, 154 orbits across 90 unique days were identified.

Bow Shock Current Closure Through the Magnetosheath for Non‐Zero IMF By—Results From Hybrid Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The bow shock current (BSC) flows on the bow shock due to the compression of the interplanetary magnetic field (IMF) across the shock. Although previous studies have shown that the BSC can connect to magnetospheric current systems via the magnetosheath, it is still not known how this happens.

MMS Observations of Multi‐Species Wave‐Particle Interactions and Rapid Foreshock Evolution

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The ion foreshock is the region upstream of Earth's bow shock where magnetic field lines connect to the quasi‐parallel shock surface. Within this region, there exist a variety of backstreaming ion populations from the shock ramp that can generate ultra‐low frequency (ULF) waves through wave‐particle interactions. In this work, we use data from

Excitation of Large Amplitude Compressional ULF Waves in the Magnetosphere by Solar Wind Pressure Spikes and IMF Southward Turning

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...
