Magnetopause energy and mass transfer: results from a global MHD simulation [PDF]

Annales Geophysicae, 2006
We use the global MHD model GUMICS-4 to investigate the energy and mass transfer through the magnetopause and towards the closed magnetic field as a response to the interplanetary magnetic field (IMF) clock angle θ=arctan (BY/BZ), IMF magnitude ...

Particle orbits at the magnetopause: Kelvin-Helmholtz induced trapping

, 2019
The Kelvin-Helmholtz instability (KHI) is a known mechanism for penetration of solar wind matter into the magnetosphere. Using three-dimensional, resistive magnetohydrodynamic simulations, the double mid-latitude reconnection (DMLR) process was shown to ...

MeV magnetosheath ions energized at the bow shock [PDF]

, 2001
A causal relationship between midlatitude magnetosheath energetic ions and bow shock magnetic geometry was previously established for ion energy up to 200 keV e−1 for the May 4, 1998, storm event.

Asymmetrically Distributed Kelvin‐Helmholtz Instability at Venusian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The asymmetric distribution of Kelvin‐Helmholtz (KH) instability at Venusian ionopause is investigated using a multifluid model. Results show that KH instability distributes asymmetrically, preferentially developing in the −E (anti‐parallel to the interplanetary electric field) hemisphere.

A linear perturbation analysis of magnetopause motion in the Newton-Busemann limit [PDF]

Annales Geophysicae, 1995
The response of the magnetopause surface to time-varying solar wind dynamic pressure is examined. We argue that to a first approximation the magnetopause surface may be considered as analogous to an elastic membrane. Upon displacement from equilibrium

Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Juno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of‐flight data into contributions from individual ion species using species‐dependent fits. At the

The azimuthal extent of three flux transfer events [PDF]

Annales Geophysicae, 2008
In early 2006, the Cluster spacecraft crossed the dayside magnetopause twice each orbit with the spacecraft at their largest separation of the entire mission (~10 000 km).

Kinetic-scale magnetic turbulence and finite Larmor radius effects at Mercury

, 2011
We use a nonstationary generalization of the higher-order structure function technique to investigate statistical properties of the magnetic field fluctuations recorded by MESSENGER spacecraft during its first flyby (01/14/2008) through the near Mercury ...

Asymmetric magnetic reconnection with a flow shear and applications to the magnetopause [PDF]

, 2015
We perform a theoretical and numerical study of anti-parallel 2D magnetic reconnection with asymmetries in the density and reconnecting magnetic field strength in addition to a bulk flow shear across the reconnection site in the plane of the reconnecting

Universal Time Influence on Stormtime Magnetosphere Ionosphere Coupling

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract The offset between Earth's magnetic and rotational axes introduces a diurnal dependence in the high‐latitude EUV exposure of the northern hemisphere (NH) and southern hemisphere (SH). This variation raises the question: Does the Universal Time (UT) of geomagnetic storm onset impact its geospace consequences?
