Statistics of Solar White-light Flares. I. Optimization and Application of Identification Methods
The Astrophysical JournalWhite-light flares (WLFs) are energetic activity in the stellar atmosphere. However, observed solar WLFs are relatively rare compared to stellar WLFs or solar flares observed at other wavelengths, which limits our further understanding of solar/stellar ...

The Efficiency of Electron Acceleration during the Impulsive Phase of a Solar Flare
The Astrophysical Journal Letters, 2023 Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in solar flare (and similar astrophysical settings) presents a major challenge.

The effect of flares on total solar irradiance
, 2010 Flares are powerful energy releases occurring in stellar atmospheres. Solar flares, the most intense energy bursts in the solar system, are however hardly noticeable in the total solar luminosity.

Commission 10: Solar Activity [PDF]
, 2007 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 ...

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract The magnetic reconnection rate at the magnetopause is crucial for solar wind and magnetosphere coupling. However, direct measurement is challenging due to inherent uncertainties and limited electron diffusion region statistics, hindering understanding of the guide field's influence on the normalized reconnection rate.

Using the Maximum X-ray Flux Ratio and X-ray Background to Predict Solar Flare Class
, 2015 We present the discovery of a relationship between the maximum ratio of the flare flux (namely, 0.5-4 Ang to the 1-8 Ang flux) and non-flare background (namely, the 1-8 Ang background flux), which clearly separates flares into classes by peak flux level.

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract High‐energy particles are prevalent in space, and magnetic reconnection is one of the physical processes responsible for their generation. The heating and acceleration of ions and electrons typically occur respectively in the ion diffusion region and the electron diffusion region.

The correlation between soft and hard X-rays component in flares: from the Sun to the stars
, 2007 In this work we study the correlation between the soft (1.6--12.4 keV, mostly thermal) and the hard (20--40 and 60--80 keV, mostly non-thermal) X-ray emission in solar flares up to the most energetic events, spanning about 4 orders of magnitude in peak ...

COMPTEL solar flare measurements [PDF]
, 1996 We review some of the highlights of the COMPTEL measurements of solar flares. These include images of the Sun in γ rays and neutrons. One of the important features of the COMPTEL instrument is its capability to measure weak fluxes of γ rays and neutrons ...

Energy Landscape in Iraq: Current Status, Research Review, and Policy Insights
Energy Science &Engineering, Volume 14, Issue 1, Page 625-678, January 2026.Renewable energy currently contributes a small fraction to Iraq's electricity mix, with 3.39% from hydropower and 0.059% from solar, while thermal power dominates at 96.6%. Significant untapped potential exists across solar, wind, biomass, geothermal, wave, and blue energy, highlighting opportunities for a low‐carbon, technoeconomically viable energy ...
