Statistical Survey of Fast Magnetosonic Waves in the L < 2 Region

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Fast magnetosonic waves are electromagnetic waves with frequencies ranging from a few Hertz to several hundred Hertz, observed primarily near the magnetic equator. Recent studies demonstrate that magnetosonic waves can propagate into the L<2 $L< 2$ region, while their distributions and propagation properties there remain unclear.

Wave Heating of Magnetotail Current Sheet Electrons at Mars

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The Martian magnetotail current sheet serves as a critical pathway for ionospheric ion escape. Contrary to the conventional view that external magnetic pressure is balanced mainly by internal ion thermal pressure, we present novel observations from the Mars Atmosphere and Volatile Evolution spacecraft of an electron‐dominated pressure balance ...

Correlation between the solar wind speed and the passage of poleward-moving auroral forms into the polar cap

Frontiers in Astronomy and Space Sciences
In 1961, Dungey suggested that magnetic reconnection occurs due to the solar-terrestrial interaction. The interplanetary magnetic field (IMF) is thought to merge with Earth’s geomagnetic field (GMF).

Direct Observations of Acceleration of Planetary Ions From Mars' Ionosphere Through Magnetic Reconnection When IMF Rotates

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Mars lacks an intrinsic global magnetic field but possesses crustal magnetic anomalies and an atmosphere. Mars' ionosphere, resulted from interactions between Mars' atmosphere and solar radiation, directly interacts with solar wind and interplanetary magnetic field (IMF). However, the mechanisms governing ion acceleration and escape from Mars'

The Ionosphere of Uranus as Revealed by JWST

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The first spectroscopic observations of Uranus by the James Webb Space Telescope were obtained in January 2023. Using these observations, we explored the physical properties of the planet's ionosphere through the analysis of near‐infrared H3+ ${\mathrm{H}}_{3}^{+}$ spectra.

Excitation of Whistler‐Mode Waves by an Electron Temperature Anisotropy in a Laboratory Plasma

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Naturally occurring whistler‐mode waves in near‐Earth space play a crucial role in accelerating electrons to relativistic energies and scattering them in pitch angle, driving their precipitation into Earth's atmosphere. Here, we report on the results of a controlled laboratory experiment focusing on the excitation of whistler waves via ...
