Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

Advanced Physics Research, Volume 5, Issue 10, October 2026.
This diagram illustrates the wavy flow configuration of the model in a Cartesian coordinate system. It represents the heat and mass transfer characteristics of ternary hybrid nanofluids over a vertically wavy surface in the presence of an induced magnetic field and double‐diffusive mixed convection.

Heliospheric Diffusion of Stochastic Parker Spirals in Radially Evolving Solar Wind Turbulence

The Astrophysical Journal
 We present a stochastic field line mapping model where the interplanetary magnetic field lines are described by a density distribution function satisfying a Fokker–Planck equation that is solved numerically.

Ionospheric Scintillation Induced by Hot Flow Anomalies via Particle Precipitation

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Ionospheric scintillation disrupts trans‐ionospheric radio signals and represents significant challenges for critical communication and navigation systems. Here we document that hot flow anomalies (HFAs), transient disturbances formed near Earth's bow shock, can contribute to scintillation near the cusp.

Statistical Mapping of ULF Wave Power in the Vicinity of Earth's Bow Shock Using Cluster Magnetic Field Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ultra‐low frequency (ULF) waves with frequencies 10–140 s are a characteristic feature of the foreshock, playing important roles in transient formation, shock reformation, and particle acceleration. We utilize 23 years of Cluster data to map ULF wave power and compressibility in the vicinity of Earth's bow shock, combining Cluster data with ...

A Fokker–Planck Framework for Studying the Variability of the Magnetic Field Direction in the Alfvénic Streams of the Solar Wind

The Astrophysical Journal Letters
Turbulent 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

Kelvin–Helmholtz Spectral Redistribution by Flow and Density Structure at the Dusk Dayside Magnetopause

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract We study the development of the Kelvin‐Helmholtz instability (KHI) along the dusk dayside Earth's magnetopause with and without the presence of enhanced plasma density at the shear interface. Using three‐dimensional MAGE global simulations, we establish general KHI growth rate diagrams, which depend sensitively on the transverse profiles of ...

Radial evolution of cross helicity at low and high latitudes in the solar wind [PDF]

, 2005
We employ a turbulence transport theory to the radial evolution of the solar wind at both low and high latitudes. The theory includes cross helicity, magnetohydrodynamic (MHD) turbulence, and driving by shear and pickup ions. The radial decrease of cross

Third-moment descriptions of the interplanetary turbulent cascade, intermittency and back transfer [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015
We review some aspects of solar wind turbulence with an emphasis on the ability of the turbulence to account for the observed heating of the solar wind. Particular attention is paid to the use of structure functions in computing energy cascade rates and their general agreement with the measured thermal proton heating.

Propagation Dynamics of Fast Electron Beam and Its Electron Cyclotron Maser Emission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Fast electron beams (FEBs) and coherent radio bursts both are very common plasma activity phenomena in the cosmos. The electron cyclotron maser (ECM) instability driven by FEBs trapped in magnetic fields can directly amplify radio wave radiations.

Observation of Kinetic Alfvén Waves inside an Interplanetary Coronal Mass Ejection Magnetic Cloud at 1 au

The Astrophysical Journal
Recent advancements have significantly enhanced our grasp of interplanetary coronal mass ejections (ICMEs) in the heliosphere. These observations have uncovered complex kinematics and structural deformations in ICMEs, hinting at the possible generation ...
