Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

AMPERE Observations of the Asymmetry Toward Stronger Birkeland Currents in the Northern Hemisphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We quantify the asymmetry between the Birkeland currents (also known as field‐aligned currents) in the Northern and Southern Hemispheres. We use data from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) in 2010–2024 inclusive for both hemispheres, compute the observed asymmetry, and then subtract the modeled

On the North‐South Symmetry of the Chorus Source Region: Conjugate Observations by the Cluster Spacecraft

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Chorus waves are arguably the most important electromagnetic emissions in the Earth's magnetosphere, being responsible for both energization and loss of radiation belt electrons. Chorus generation, inherently related to nonlinear wave‐particle interactions, as well as the frequency‐time shapes of individual elements forming it, are not yet ...
