A Parametric Study of Solar Wind Properties and Composition Using Fluid and Kinetic Solar Wind Models

The Astrophysical Journal
The physical processes in the solar corona that shape the solar wind remain an active research topic. Modeling efforts have shown that energy and plasma exchanges near the transition region play a crucial role in modulating solar wind properties ...

Predicting Electrically Generated Hydrogen Oxides From Ultraviolet Radiation Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Electrical discharges such as lightning and corona discharges generate extreme amounts of hydroxyl radical (OH), the atmosphere's most important oxidizer, enough for electrical discharges to be a globally significant source of OH. However, there are few field measurements of electrically generated OH (LOH), hindering attempts to better ...

Localized Heating and Dynamics of the Solar Corona due to a Symbiosis of Waves and Reconnection

The Astrophysical Journal
The Sun’s outer atmosphere, the corona, is maintained at mega-Kelvin temperatures and fills the heliosphere with a supersonic outflowing wind. The dissipation of magnetic waves and direct electric currents are likely to be the most significant processes ...

The Influence of Applied Voltage on Drying Kinetics, Quality, and Mathematical Modeling of Ginger During Electrohydrodynamic (EHD) Drying

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
The graphical abstract systematically outlines the experimental design and major findings of this study. On the left is the conventional natural air‐drying method used as the control group; the middle section illustrates the Electrohydrodynamic (EHD) drying process under voltage gradients of 13, 17, and 21 kV, followed by four analytical dimensions ...

Power-law Indices of EUV Intensity Power Spectrum in Flaring Coronal Active Regions

The Astrophysical Journal
Solar intensity power spectra are usually characterized by colored noise, with the spectral energy following a segmented power-law function of frequency, S ( f ) ∝ f ^− ^α , over different frequency ranges. Typically, the power-law index exceeds 1 in the

Predicting Geomagnetic Activity in the Ascending and Declining Phases of the Solar Cycle

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Most predictions of space climate, that is, the long‐term behavior of the solar‐terrestrial environment, have focused on forecasting the 11‐year sunspot cycle. Geomagnetic activity, on the other hand, has mainly been predicted in shorter, space weather timescales of up to days to weeks.

Magnetic Field Variability as a Consistent Predictor of Solar Flares

The Astrophysical Journal
Solar flares are intense bursts of electromagnetic radiation that occur due to a rapid destabilization and reconnection of the magnetic field. While preflare signatures and trends have been investigated from magnetic observations prior to flares for ...

Electronic and Structural Effects in Porphyrin Metal–Organic Framework Sensitizers for Solid‐State Dye‐Sensitized Solar Cells

ChemPhysChem, Volume 27, Issue 14, 29 July 2026.
Porphyrin metal–organic frameworks (PMOFs) offer structurally ordered and compositionally tunable platforms for sensitized photovoltaics. Titanium‐ and indium‐based PMOFs, together with a tin‐doped indium analog, were investigated as photosensitizers in solid‐state dye‐sensitized solar cells (ssDSSCs). Electrochemical and optical measurements confirmed

Analysis of CME Interactions in Solar Corona Combining Coronagraphic Observations with Wide-field Imagers from Solar Orbiter and Parker Solar Probe

The Astrophysical Journal
Accurately determining the trajectory of coronal mass ejections (CMEs) is vital for space weather forecasting and assessing their potential impact on Earth. CMEs often deviate from a radial path, due to local pressure gradients or interactions with other

Unraveling the Fine‐Scale Tapestry of Solar Wind at 1AU

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Solar wind is a complex network of distinct magnetic flux tubes, each contained and separated by a current sheet. In this study, more than 50,000 current sheets in the solar wind are identified and characterized for the first time, using multi‐point Cluster observations during solar minimum and maximum intervals.
