The Effect of the Parametric Decay Instability on the Morphology of Coronal Type III Radio Bursts

The Astrophysical Journal Letters, 2023
The nonlinear evolution of Alfvén waves in the solar corona leads to the generation of Alfvénic turbulence. This description of the Alfvén waves involves parametric instabilities where the parent wave decays into slow mode waves giving rise to density ...

Beyond Electrochemical Innovation: Prioritizing Industry Standard Abuse Testing for Safe Lithium Metal Batteries

Energy Technology, Volume 14, Issue 7, July 2026.
This critical review evaluates recent material and architectural innovations in lithium metal batteries against the strict frameworks of industry standard abuse testing. By analyzing the disconnect between benchtop electrochemical performance and macroscale safety validation, the review highlights the urgent need to transition from low scale cell ...

Radio Measurements of the Magnetic Field in the Solar Chromosphere and the Corona

Frontiers in Astronomy and Space Sciences, 2021
The structure of the upper solar atmosphere, on all observable scales, is intimately governed by the magnetic field. The same holds for a variety of solar phenomena that constitute solar activity, from tiny transient brightening to huge Coronal Mass ...

Heat and Dust Impacts on the Health of Refugees in Zaatari Refugee Camp

GeoHealth, Volume 10, Issue 7, July 2026.
Abstract Climate‐linked heatwaves and dust storms can exacerbate non‐communicable disease (NCD) morbidity, yet quantitative evidence from displacement settings remains limited. We assessed short‐term impacts of heat and dust events on symptom burden among Syrian refugees with non‐communicable diseases (NCDs) in Jordan's Zaatari Camp.

Development and application of a global magnetic field evolution model for the solar corona [PDF]

, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Are Nonthermal Velocities in Active Region Coronal Loops Anisotropic?

The Astrophysical Journal, 2023
We have measured line widths in active region coronal loops in order to determine whether the nonthermal broadening is anisotropic with respect to the magnetic field direction. These nonthermal velocities are caused by unresolved fluid motions.

Interplanetary Tracking of the 23 March 2024 CME: Computer Tomographic Analyses of IPS, White‐Light, and Type II Radio Burst Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract We analyze the propagation of a coronal mass ejection (CME) observed on 23 March 2024, at 01:25 UT by SOHO/LASCO using a multi‐instrument and multi‐method approach. The study combines Interplanetary Scintillation (IPS), type II radio bursts, white‐light, in‐situ observations, and 3D tomographic reconstruction of the inner heliospheric density.

Influence of Ionization on the Polytropic Index of the Solar Atmosphere within Local Thermodynamic Equilibrium Approximation

The Astrophysical Journal
An initial theoretical attempt to explain the observed decrease of the polytropic/adiabatic index γ in the solar corona has been accomplished. The chemical reactions of the ionization–recombination processes in local thermodynamic equilibrium (LTE) of a ...

Muon Flux Fluctuations and Solar Phenomena Using Regional Geomagnetic Indices With a Cosmic Ray Detector in Mexico City

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The data from a cosmic ray (CR) detector in Mexico City were collected over a period of 2 years from September 2023 to September 2025, during the maximum phase of Solar Cycle 25. The CR detector consists of an array of scintillators and measures the muonic component of secondary CRs.

Solar cycle dependence of scaling in solar wind fluctuations [PDF]

, 2008
In this review we collate recent results for the statistical scaling properties of fluctuations in the solar wind with a view to synthesizing two descriptions: that of evolving MHD turbulence and that of a scaling signature of coronal origin that ...
