Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract By analyzing continuous Magnetospheric Multiscale observations at the magnetopause boundary layer, combining both magnetohydrodynamic and kinetic signatures, we have successfully captured dynamic magnetic reconnection processes in exceptional detail. Our results demonstrate that magnetic reconnection exhibits rapid transitions between distinct

Simulation Study of Chorus Wave Modulation and Associated Electron Precipitation
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract The modulation of chorus waves on several‐second timescales in Earth's magnetosphere plays a crucial role in modulating electron precipitation intensity, leading to the formation of pulsating aurora. However, the physical mechanism underlying chorus modulation remains not fully understood.

, 2015 The origin of the near-infrared (NIR) HI emission lines in young stellar objects are not yet understood. To probe it, we present multi-epoch LBT-LUCIFER spectroscopic observations of the Pa{\delta}, Pa{\beta}, and Br{\gamma} lines observed in the Herbig ...

Auroral Asymmetry Associated With the South Atlantic Anomaly
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract The South Atlantic anomaly (SAA) exerts a weakening effect on magnetic field strength on Earth, however, little is known of its effect on the auroral spatial distribution and temporal evolution. Using Defense Meteorological Satellite Program/Special Sensor Ultraviolet Spectrographic Imager ultraviolet data spanning 2016–2023, we investigated ...

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract A systems science approach based on canonical correlation analysis (CCA) is applied as a new, behavioral way to validate global geospace models. The biggest novelty of the technique is that it validates models at a system level, whereby a side‐by‐side comparison is performed of CCA applied to a 30‐day observational and the corresponding ...

, 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 ...

Modelling the magnetosphere of Mercury [PDF]
A model magnetosphere for Mercury is presented using an upstream image-dipole and nightside 2-dimensional tail current sheet method. The tail field is represented by an analytical formulation.

Axisymmetric force-free magnetosphere of a pulsar. I. The structure close to the magnetic axis
, 2012 The stationary axisymmetric force-free magnetosphere of a pulsar is studied analytically. The pulsar equation is solved in the region close to the magnetic axis. Proceeding from linearization of the current function in the axial region, we find the axial

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract The magnetopause boundary layer often exhibits flux enhancements in ≳30 $\gtrsim 30$ keV electrons. Intriguingly, these enhancements frequently occur in the afternoon sector, which is typically magnetopause‐shadowed. They are usually attributed to local production by dayside reconnection, wave‐particle interactions, or radial diffusion by ...
