, 2015 The interplanetary magnetic field near has a characteristic "sector" structure that reflects its polarity relative to the solar direction. Typically we observe large-scale coherence in these directions, with two or four "away" or "towards" sectors per ...

How Does the Magnetosphere‐Ionosphere Current System Respond to Solar Flares?
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract While the isolated effects of solar flares on low‐latitude ionospheric electrodynamics have been well documented, the coupled system response of the equatorial electrojet (EEJ), auroral electrojet (AEJ), field‐aligned currents (FACs), and asymmetric ring current (ASY‐H) remains poorly understood.

The Astrophysical JournalThe curvature of the magnetic field plays a crucial role in magnetic confinement, magnetic reconnection, particle heating, and acceleration. Though the magnetic field curvature has been sufficiently investigated in the terrestrial magnetosheath, there is

Modelling interplanetary CMEs using magnetohydrodynamic simulations [PDF]
Annales Geophysicae, 2002 The dynamics of Interplanetary Coronal Mass Ejections (ICMEs) are discussed from the viewpoint of numerical modelling. Hydrodynamic models are shown to give a good zero-order picture of the plasma properties of ICMEs, but they cannot model the ...

Frontiers in Physics, 2021 Low–frequency fluctuations in the interplanetary medium have been extensively investigated and described in the framework of turbulence, and the observed universal scaling behavior represents a clear signature of the underlying energy cascade.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Substorms are often described by a loading‐unloading cycle, where onset follows gradual accumulation of solar wind magnetic flux in the magnetosphere. Yet observations indicate that intense substorms can also be directly driven, though the underlying mechanism remains unresolved.

The Astrophysical Journal LettersTurbulent rotations of the magnetic field vector are observed in the Alfvénic streams of the solar wind where the magnetic field strength remains close to a constant. They can lead to reversals of the radial magnetic field component or switchbacks. It is

Scaling Anisotropy with Stationary Background Field in Near-Sun Solar Wind Turbulence
The Astrophysical Journal, 2023 The scaling of magnetic fluctuations provides crucial information for the understanding of solar wind turbulence. However, the observed magnetic fluctuations contain not only turbulence but also magnetic structures, leading to the violation of time ...

Martian Atmospheric Loss Through Foreshock Transient Events
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

The Astrophysical Journal, 2023 Interstellar neutral atoms enter the heliosphere at a relatively slow speed corresponding to the motion of the Sun through the local interstellar medium, which is approximately 25 km s ^−1 .
