Theory and Modeling of Large Scale Plasmapause Surface Waves

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract The plasmapause in Earth's magnetosphere represents the boundary between the plasma which co‐rotates with the Earth (plasmasphere), and the more tenuous plasmatrough outside. The density change across the plasmapause can be large, changing by approximately 1–2 orders of magnitude depending on the prevailing conditions. This would suggest it to

AKR Observations From All Local Times Indicate Substorm Activity

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract Auroral Kilometric Radiation (AKR) is known to present emission at lower frequencies near substorm onset, corresponding to activation of higher altitude sources along auroral magnetic field lines and acting as a proxy of the vertical distribution of acceleration processes during these events.

Stability of the Earth's Dayside Magnetosheath: Effects of Upstream Solar Wind Structures and Downstream Jets

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract The constant stream of plasma from the Sun, the solar wind, forms a bow shock as it interacts with Earth's magnetic field. The plasma properties change drastically as it crosses the shock and enter the downstream magnetosheath. This extended region hosts various kinetic ion plasma instabilities, such as mirror modes, ion cyclotron waves, and ...
