Validation of Long-term Solar Coronal Modeling Using FORWARD

The Astrophysical Journal Supplement Series
This research aims to evaluate the capabilities of two of the most widely used coronal models over multiple solar cycles and to study variations in solar coronal structures over an extended period across multiple channels. We have created a comprehensive

The Impact of Cosmic Ray Injection on Magnetic Flux Tubes in a Galactic Disk

The Astrophysical Journal, 2023
In a seminal paper, Parker showed the vertical stratification of the interstellar medium (ISM) is unstable if magnetic fields and cosmic rays provide too large a fraction of pressure support. Cosmic ray acceleration is linked to star formation, so Parker’

The Spatial Localization of Storm‐Time ULF Waves Due To Plasmaspheric Plumes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The generation and propagation of Ultra Low Frequency (ULF) waves are intrinsically coupled to the cold plasma population in the terrestrial magnetosphere. During geomagnetic storms, extreme reconfigurations of the cold plasma create a complex and dynamic system that drastically modifies this coupling.

How Switchbacks Can Maintain a Longer Time in the Interplanetary Space

The Astrophysical Journal
Parker Solar Probe, the closest spacecraft to the Sun, has renewed our understanding of the solar corona and the interplanetary space. One of its important findings is the prevalence of switchbacks, which display localized magnetic reversals along the ...

Dynamical Solar Wind Forecasting Using In Situ Solar Wind Speed Observations

Space Weather, Volume 24, Issue 11, November 2026.
Abstract Accurate prediction of the ambient solar wind at Earth is a key requirement for space‐weather forecasting but is limited by uncertainties in coronal boundary conditions and, to a lesser extent, heliospheric transport. We present a quantitative assessment of a solar wind forecast that uses near‐Earth in situ solar wind observations to estimate ...

Enhancement of Magnetic Flux Transferred to the Magnetotail Due to a Storm‐Time Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Properties of Current Sheets in Two-dimensional Tearing-mediated Incompressible Magnetohydrodynamic Turbulence

The Astrophysical Journal
It is well known that the nonlinear evolution of magnetohydrodynamic (MHD) turbulence generates current sheets. In the solar wind turbulence, current sheets are frequently observed, and they are believed to be an important pathway for the turbulence ...

Comparison between axisymmetric numerical magnetohydrodynamical simulations and self-similar solutions of jet-emitting disks

Astronomy & Astrophysics
Context. Turbulent accretion disks threaded by a large-scale vertical field near equipartition can drive tenuous and fast self-confined jets. Self-similar solutions of these jet-emitting disks (JEDs) have been known for a long time and provide the ...

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.

Nanofluid Heat Transfer Enhancement in Porous Media With Geometric and Particle Morphology Effects

Engineering Reports, Volume 8, Issue 10, October 2026.
Levenberg–Marquardt neural network predicts Cu–water nanofluid flow and heat transfer in a converging/diverging porous channel with Darcy–Forchheimer drag, nanoparticle shape effects (sphere, column, lamina), and viscous dissipation. ABSTRACT Efficient thermal management in porous, nanofluid‐filled systems is essential for applications such as compact ...
