The Speed of Interplanetary Shocks Through the Magnetosheath: A Toy Model
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Before interacting with the magnetosphere, an interplanetary shock travels through the magnetosheath where its speed and shape are modified. Previous studies have reported widely different answers to the question of the speed of an interplanetary shock in the magnetosheath. Observational studies generally answer this question “macroscopically”,

Magnetospheric "anti-glitches" in magnetars [PDF]
arXiv, 2013 We attribute the rapid spindown of magnetar 1E 2259+586 observed by Archibald et al. (2013), termed the "anti-glitch", to partial opening of the magnetosphere during the X-ray burst, followed by changes of the structure of the closed field line region. To account for the observed spin decrease during the X- ray flare all that is needed is the transient

Long-term evolution of the force-free twisted magnetosphere of a magnetar [PDF]
, 2017 We study the long-term quasi-steady evolution of the force-free magnetosphere of a magnetar coupled to its internal magnetic field. We find that magnetospheric currents can be maintained on long timescales of the order of thousands of years. Meanwhile, the energy, helicity and twist stored in the magnetosphere all gradually increase over the course of ...

Sub‐Auroral Heating at Jupiter Following a Solar Wind Compression
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Jupiter's polar aurorae deliver significant heating at the poles, thought to spread across the planet through atmospheric winds. Additionally, ground‐based Keck observations have revealed a large‐scale high‐temperature region, spatially distinct from the aurorae.

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Recently, electron‐only reconnection, in which there is no obvious ion bulk flow and ion heating, has been pervasively observed in the Earth's magnetosphere. In this Letter, we realize electron‐only reconnection with a guide field in the Keda Linear Magnetized Plasma (KLMP) device.

Solar wind entry into the high-latitude terrestrial magnetosphere during geomagnetically quiet times
Nature Communications, 2013 An understanding of the transport of solar wind plasma into and throughout the terrestrial magnetosphere is crucial to space science and space weather. For non-active periods, there is little agreement on where and how plasma entry into the magnetosphere

, 2014 This book belongs to a series of online books summarizing the recent state Topological Geometrodynamics (TGD) and its applications. TGD can be regarded as a unied theory of fundamental interactions but is not the kind of unied theory as so called GUTs constructed by graduate students at seventies and eighties using detailed recipes for how to reduce ...

The Eddy Flux Transport of the Magnetohydrodynamic Quasi‐Geostrophic Disturbances
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract The classic Eliassen‐Palm (E‐P) flux in the geophysical fluid dynamics is a vector to qualify the eddy momentum and heat flux transport by Rossby waves in the latitude‐height plane. In this investigation, we derive two magnetic E‐P fluxes to quantify the eddy energy transport by magnetic Rossby waves by using magnetohydrodynamic quasi ...

Dynamics of the Earth's Radiation Belts and Inner Magnetosphere
, 2013 Trapped by Earth's magnetic field far above the planet's surface, the energetic particles that fill the radiation belts are a sign of the Sun's influence and a threat to our technological future.

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Plasmaspheric hiss plays an important role in the electron precipitation and the slot formation in radiation belts. Recent studies show the whistler‐mode waves can be guided in the density irregularities, performing parallel propagation. Therefore, the resonance between ducted waves and energetic electrons can expand to higher latitudes, and ...
