Magnetotail Configuration Under Northward IMF Conditions

Journal of Geophysical Research: Space Physics, 2020
Abstract Due to the sparsity of space probes, it is still not clear on how the magnetic structure of the magnetotail looks like and how it evolves when the interplanetary magnetic field (IMF) directs northward.

Magnetotail energy dissipation during an auroral substorm [PDF]

Nature Physics, 2016
Violent releases of space plasma energy from the Earth's magnetotail during substorms produce strong electric currents and bright aurora. But what modulates these currents and aurora and controls dissipation of the energy released in the ionosphere? Using data from the THEMIS fleet of satellites and ground-based imagers and magnetometers, we show that ...

Evolution of Open Magnetic Flux During Substorms: The Effects of Dipole Tilt Angle

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract There is a long‐standing debate on the causes of the semiannual variation of geomagnetic activity. One of the prevailing hypotheses is that the Earth's dipole tilt angle Ψ ${\Psi }$ modulates the dayside reconnection rate, causing the so‐called equinoctial effect. Here we perform the first large‐scale statistical study to test this hypothesis.

Response of Martian Tail Lobes to Heliospheric Current Sheet: Tianwen-1 and MAVEN Joint Observations

The Astrophysical Journal Letters
Martian magnetotail lobes, mainly formed by the draped interplanetary magnetic field extending downstream in the tailward direction, are largely controlled by the solar wind and respond sensitively to variations in upstream drivers.

Fully Kinetic Simulations of Ion‐Acoustic Waves in Asymmetric Reconnection With Cold Ions

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract In collisionless plasma, ion‐acoustic wave (IAW) is an important candidate for enhancing resistivity and viscosity, yet their presence and role in magnetic reconnection remain poorly understood. Here, we employ 2.5‐D particle‐in‐cell simulations to investigate IAWs in asymmetric magnetopause reconnection involving a cold ion population ...

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Hiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth's inner magnetosphere. While previous studies have linked hiss wave enhancements in the outer plasmasphere (just inside the plasmapause) to electron injections during substorms, their evolution across various substorm phases ...

Solar Activity Dependence of the Dayside Lunar Surface Potential in the Terrestrial Magnetotail

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract On the dayside of the Moon, the surface potential is primarily determined by (a) photoelectron emission by solar radiation and (b) the ambient plasma environment. Both of these drivers have large variability, but the resulting variability of the lunar surface potential has not been fully characterized yet.

The Energetic Oxygen Ion Beams in the Martian Magnetotail Current Sheets: Hints From the Comparisons Between Two Types of Current Sheets

Geophysical Research Letters
Using data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we explore the plasma properties of Martian magnetotail current sheets (CS), to further understand the solar wind interaction with Mars and ion escape.
