Revealing the CME Impact on the Martian Nightside Ionosphere Based on MAVEN and Tianwen-1 Observations

The Astrophysical Journal
Due to the absence of an Earth-like dipole magnetic field, the impact of coronal mass ejections (CMEs) on the Martian nightside ionosphere differs from that on Earth and is still not well understood.

Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to

Earthward Transport of Lunar Metallic Ions: Implications of Heavy Ions in the Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Low‐charge‐state heavy ions in Earth's magnetosphere were thought to originate from the ionosphere. However, Observations from the Geotail mission have detected the presence of singly charged metallic ions, such as Fe+ ${\mathrm{F}\mathrm{e}}^{+}$, whose abundances vary depending on the Moon's location, alongside their density ratios to O ...

Ionospheres and atmosphere of non-magnetic planets and solar wind interaction: Part I - Venus

, 2002
The solar-planetary interaction is unique for non-magnetic planets, since the solar wind interacts directly with the atmospheres and ionospheres of these planets.

Chaos gated tunneling drives molecular reactivity in astrophysical environments

Discover Space
Accurate modeling of ion-molecule reaction networks is essential for understanding the chemical evolution of planetary ionospheres, particularly for giant planets where proton-transfer chains drive atmospheric composition.

Impacts of the GDS 2018 Global Dust Storm on Martian Ionosphere‐Thermosphere Coupling via Atmospheric Tides

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract In this study, we investigate the ionospheric and thermospheric responses to the 2018 Mars global dust storm (GDS 2018) by examining atmosphere–ionosphere coupling through tidal structures. Using Mars Atmosphere and Volatile EvolutioN Neutral Gas and Ion Mass Spectrometer observations, we analyze tidal amplitudes, phases, and inter‐species ...

Atmospheric Distribution and Escape of Odd Nitrogen on Mars

The Astronomical Journal
The total nitrogen budget in the Martian upper atmosphere is significantly contributed by the presence of odd nitrogen, mainly in the form of NO and ground-state or excited-state N.
