Uncertainties in Theoretical Chorus Chirping Rates: A Comparative Analysis
Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Whistler‐mode chorus waves play a critical role in the dynamics of energetic electrons in the inner magnetosphere. Extensive theoretical research has been conducted to explain the frequency chirping of chorus waves, with two primary theoretical chirping rates proposed: one associated with magnetic field inhomogeneity and the other linked to ...

Field‐Aligned Currents and Auroral Precipitation During the Terrestrial Alfvén Wing State
Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract When sub‐Alfvénic (Alfvén Mach number MA< ${\mathrm{M}}_{A}< $1) plasmas impact Earth, Alfvén wings (AWs) develop. A Multiscale Atmosphere Geospace Environment simulation of the April 2023 storm, validated by Active Magnetosphere and Planetary Electrodynamics Response Experiment data, reveals the field‐aligned‐current (FAC) generation ...

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract This study investigates the formation of a newly identified storm‐time ionospheric phenomenon, the bubble‐like ionospheric super‐depletion structure (BLISS) in F‐region plasma densities. The observed BLISS initiates from the magnetic dip equator in the post‐sunset region and expands westward and poleward, reaching midlatitudes of ∼40°, which ...

Ion Escape From Degenerate Induced Magnetospheres: The Case of Mars
Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract When the cone angle of the interplanetary magnetic field (IMF) becomes small, induced magnetospheres of unmagnetized planets degenerate. Using hybrid simulations, we study ionospheric ion escape in a 4° cone angle case and compare it with the nominal 55° cone angle (Parker spiral) case. The total escape rate is 1.7×1025 $1.7\times 1{0}^{25}$ s−

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract Solar wind directional discontinuities can generate transient mesoscale structures such as foreshock bubbles and hot flow anomalies (HFAs) upstream of Earth's bow shock. These structures can have a global impact on near‐Earth space, so understanding their formation conditions is essential.
