Planetary magnetospheres [PDF]

A concise overview is presented of our understanding of planetary magnetospheres (and in particular, of that of the Earth), as of the end of 1981. Emphasis is placed on processes of astrophysical interest, e.g., on particle acceleration, collision-free ...

The Keplerian regime of charged particles in planetary magnetospheres

Physica D: Nonlinear Phenomena, 2004
The dynamics of a charged particle orbiting around a rotating magnetic planet is studied. The system is modelled by the two-body Hamiltonian perturbed by an axially-symmetric function which goes to infinity as soon as the particle approaches the planet. The perturbation consists in a magnetic dipole field and a corotational electric field.

Observation of a Knotted Electron Diffusion Region in Earth's Magnetotail Reconnection

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Magnetic reconnection is a fundamental plasma process that alters the magnetic field topology and releases magnetic energy. Most numerical simulations and spacecraft observations assume a two‐dimensional diffusion region, with the electron diffusion region (EDR) embedded in the same plane as the ion diffusion region (IDR) and a uniform guide ...

Extreme Magnetopause Deformation Induced by High‐Speed Jet From Foreshock Transient

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract This study presents comprehensive observations of intense high‐speed jets (HSJs) and their global impacts on the inner magnetosphere and ionosphere, using multi‐satellite and ground‐based observations. Cluster‐4, located near the bow shock, observed signatures associated with foreshock transients generated by a solar wind directional ...

Mercury’s plasma environment after BepiColombo’s third flyby

Communications Physics
Understanding Mercury’s magnetosphere is crucial for advancing our comprehension of how the solar wind interacts with the planetary magnetospheres. Despite previous missions, several gaps remain in our knowledge of Mercury’s plasma environment.

Linking Very Near‐Earth Reconnection (VNERX) to Mid‐Latitude GICs: Evidence From the 7 September 2017 Storm

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.
