Efficiency of Electromagnetic Energy Transfer From Solar Wind to Ionosphere Through Magnetospheric Ultra‐Low Frequency Waves

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ultra‐low frequency (ULF) waves are a ubiquitous carrier of energy in geospace. However, their efficiency in transferring solar wind energy into the upper atmosphere remains a fundamental and not well‐understood question. This is due to their global presence, which cannot be fully quantified by spatially limited observations, and the need for ...

Effects of the 2007 Martian Global Dust Storm on Boundary Positions in the Induced Magnetosphere

The Planetary Science Journal
Mars's magnetosphere is a sensitive system, varying due to external and internal factors, such as solar wind conditions and crustal magnetic fields.

Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

Frequency Characteristics of Magnetosonic Waves Driven by Hot Ring-Beam Protons

The Astrophysical Journal
Magnetosonic (MS) waves can be generated by energetic ring-beam protons, appearing as harmonics near the local proton cyclotron frequency, in the planetary ionospheres/magnetospheres.

Planetary period oscillations in Saturn's magnetosphere: Coalescence and reversal of northern and southern periods in late northern spring

, 2016
We investigate planetary period oscillations (PPOs) in Saturn's magnetosphere using Cassini magnetic field and Saturn kilometric radiation (SKR) data over the interval from late 2012 to the end of 2015, beginning ~3 years after vernal equinox and ending ~

Baseline Climatology of Gravity Waves From ∼30 to ∼70 km Established With Lidar Observations Over a Decade at McMurdo (77.84°S, 166.67°E), Antarctica: Implications for Vertical Wave Evolution

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Lidar observations of atmospheric gravity waves (GWs) have been made spanning 14 years above McMurdo Station, Antarctica. Using these extensive observations and interleaved data processing techniques which enable bias‐free/noise‐floor‐free estimation of GW parameters, this study forms seasonal baselines for GW potential energy densities (Epm ...

Solar-wind control of the extent of planetary ionospheres [PDF]

In our solar system there are at least four magnetic planets: Earth, Jupiter, Mercury, and Mars; while at least one planet, Venus, appears to be essentially nonmagnetic. The ionospheres of the magnetic planets are imbedded in their magnetosphere and thus
