Complex dynamics of a heavy symmetrical gyroscope under a parametric nonlinear damping

This paper analyzes the chaos and coexistence of attractors of a heavy gyroscope with parametric nonlinear damping. After having found the mathematical model of the dynamics, we used the multiple scale technique to look for secondary resonances ...

Oxygen Pickup Acceleration in the Plasma Mantle Associated With Traveling Flux‐Rope Structures

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract It is well known that, in the high‐altitude cusp and mantle regions, ionospheric‐origin outflowing oxygen (O+) ions are often energized through non‐adiabatic processes, among which cyclotron resonance is considered a major mechanism. Here, based on Cluster observations, we present evidence that pickup acceleration also operates as a non ...

New Electron Population Trapped at Low Latitudes Near Jupiter

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We report observations of a low energy (<2 keV), trapped electron population near Jupiter's magnetic equator made by the Jovian Auroral Distributions Experiment (JADE) on Juno. Electron intensity peaks around the location of the minimum magnetic field magnitude along the field line that is connected to Juno.
