Dust Plumes Induced by a Time‐Varying Electron Beam

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We present laboratory results to address dust charging and lofting on the Moon and other airless planetary bodies in response to time‐varying solar wind and ultraviolet (UV) exposure. In these experiments, dust is exposed to an electron beam that varies in beam energy between 40 and 260 eV as a function of time.

Effects of flares on solar oscillation characteristics [PDF]

, 2003
We use ring diagram analysis to study the effects of solar flares on p-mode oscillation characteristics. We study the changes in the amplitude, frequency and width of acoustic modes using data before, during and after a few of the major flares during the

A Universal Scaling between Damping Time and Period of Quasi-periodic Pulsations from Solar Extreme-Ultraviolet Brightenings to X-Ray Stellar Flares

The Astrophysical Journal Letters
Recent high spatial and temporal resolution extreme-ultraviolet (EUV) imaging observations have revealed that quasi-periodic pulsations (QPPs), a ubiquitous signature of impulsive energy release in solar and stellar flares, are also present in much ...

Fine structure events in microwave emission during solar minimum

Solar-Terrestrial Physics, 2019
The solar minimum is a period with a relatively smaller number of sunspots and solar eruptions, and has been less studied before. Since the radio signal rapidly responds to the change of solar plasma and magnetic field, we perform a comprehensive ...

PREDICTION OF SOLAR FLARES USING UNIQUE SIGNATURES OF MAGNETIC FIELD IMAGES [PDF]

, 2016
Prediction of solar flares is an important task in solar physics. The occurrence of solar flares is highly dependent on the structure and topology of solar magnetic fields.

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, Volume 12, Issue 20, 26 October 2026.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...

Statistical Studies of Solar White-light Flares and Comparisons with Superflares on Solar-type Stars [PDF]

, 2017
Recently, many superflares on solar-type stars have been discovered as white-light flares (WLFs). The statistical study found a correlation between their energies (E) and durations (τ): , similar to those of solar hard/soft X-ray flares, . This indicates

Anomalous-plasmoid-ejection-induced secondary magnetic reconnection: modeling solar flares and coronal mass ejections by laser–plasma experiments

High Power Laser Science and Engineering, 2013
The driving mechanism of solar flares and coronal mass ejections is a topic of ongoing debate, apart from the consensus that magnetic reconnection plays a key role during the impulsive process.

Sparse bayesian imaging of solar flares

, 2019
We consider imaging of solar flares from NASA Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) data as a parametric imaging problem, where flares are represented as a finite collection of geometric shapes. We set up a Bayesian model in which

Commission 10: Solar Activity [PDF]

, 2005
Commission 10 aims at the study of various forms of solar activity, including networks, plages, pores, spots, fibrils, surges, jets, filaments/prominences, coronal loops, flares, coronal mass ejections (CMEs), solar cycle, microflares, nanoflares ...
