How Does the Definition of a Geomagnetic Storm Affect the Contents of the Resulting Storm List?

open access: yesSpace Weather, Volume 24, Issue 5, May 2026.
Abstract A geomagnetic storm is a significant and prolonged disturbance of the Earth's magnetic field caused by an enhancement of the ring current. Storms are typically identified using magnetic field measurements from multiple ground‐based magnetometers, and the corresponding dates and times of multiple storms can be collated to form a storm list ...

Mars' Ionospheric Response to the Onset and Early Phase of 20 May 2024 Solar Flare

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar extreme ultraviolet (EUV, 10–100 nm) and X‐ray (<10 nm) photons are the primary ionization source for the dayside Mars ionosphere. Their fluxes, especially at short wavelengths, increase significantly during solar flares. Among the series of solar flares and solar storms encountered by Earth and Mars in May 2024, one of the strongest ...

On the Million-degree Signature of Spicules

open access: yesThe Astrophysical Journal Letters
Spicules have often been proposed as substantial contributors toward the mass and energy balance of the solar corona. While their transition region (TR) counterpart has unequivocally been established over the past decade, the observations concerning the ...

Turbulence in a Coronal Loop Excited by Photospheric Motions

open access: yesAtmosphere, 2020
Photospheric motions are believed to be the source of coronal heating and of velocity fluctuations detected in the solar corona. A numerical model, based on the shell technique applied on reduced magnetohydrodynamics equations, is used to represent ...

Coronal Loop Heating by Nearly Incompressible Magnetohydrodynamic and Reduced Magnetohydrodynamic Turbulence Models

open access: yesThe Astrophysical Journal, 2023
The transport of waves and turbulence beyond the photosphere is central to the coronal heating problem. Turbulence in the quiet solar corona has been modeled on the basis of the nearly incompressible magnetohydrodynamic (NI MHD) theory to describe the ...

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 15, 17 April 2026.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

EXPLAINING INVERTED-TEMPERATURE LOOPS IN THE QUIET SOLAR CORONA WITH MAGNETOHYDRODYNAMIC WAVE-MODE CONVERSION [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT Coronal loops trace out bipolar, arch-like magnetic fields above the Sun’s surface. Recent measurements that combine rotational tomography, extreme-ultraviolet imaging, and potential-field extrapolation have shown the existence of large loops with inverted-temperature profiles, i.e., loops for which the apex temperature is a ...

Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

open access: yesAGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Observations of Mini Coronal Dimmings Caused by Small-scale Eruptions in the Quiet Sun

open access: yesThe Astrophysical Journal Letters, 2023
Small-scale eruptions could play an important role in coronal heating, generation of solar energetic particles (SEPs), and mass source of the solar wind.
