An Investigation on the Apparent North‐South Asymmetry Identified in Multiple Current Sheet Crossing Events in Jovian Dawn Outer Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Jovian magnetospheric dynamics are often believed to be mainly controlled by internal elements such as Jupiter's strong and fast‐rotating magnetic moment and Io's abundant volcanic escape, as these internal elements are powerful enough to control the magnetospheric dynamics, contrary to the internal elements of the earth's magnetosphere.

Imaging the Perpendicular Plasma Dynamics Driving a Discrete Auroral Arc

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Measurements of motions and structuring in auroral luminosity are combined with magnetically connected plasma measurements from the Reimei spacecraft to image the perpendicular plasma dynamics active above a discrete auroral arc. It is demonstrated how the inversion of optical flow patterns specifies the potential structure above regions of ...

Ion Energization and Acceleration Associated With Foreshock Bubbles: Results From a Hybrid‐Vlasov Simulation and MMS Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Foreshock Bubbles (FBs) are large‐scale transient structures found in Earth's foreshock region and are associated with foreshock‐discontinuity interaction. FBs play a significant role in accelerating and energizing plasma through various mechanisms.

Loading Non‐Maxwellian Velocity Distributions in Particle Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Numerical procedures for generating non‐Maxwellian velocity distributions in particle simulations are presented. First, Monte Carlo methods for the (r,q) $(r,q)$ distribution that generalizes flattop and Kappa distributions are discussed. Then, two rejection methods for the regularized Kappa distribution are presented, followed by a comparison

MMS Observation of Trapping of Electrons by Chorus Waves Inside a Magnetic Hole

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present an event of chorus waves embedded within a magnetic hole (MH) in the Earth's magnetosheath, observed by the Magnetospheric Multi‐Scale (MMS) mission on 1 March 2016. Unlike conventional cases where chorus waves are typically detected near the center of a magnetic depression, in this event lower‐band chorus waves appear predominantly

Thermospheric Energy and Heating Due To Upward Propagating and in Situ Generated Tides During Solar Cycle 24

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigate vertical and horizontal energy transport and associated heating in the thermosphere due to both upward propagating and in situ generated migrating and nonmigrating diurnal and semidiurnal tides over the solar cycle 24 (2009–2019).
