Electrons and X-Ray Emission of Solar Flares [PDF]
Symposium - International Astronomical Union, 1990 A statistical analysis of solar flare X-rays and interplanetary particle fluxes, measured onboard VENERA-13, 14 Spacecraft, was performed. The correlation of fluences for different manifestations of solar flares is strong, especially for fast electrons and hard and soft X-ray emissions. Frequency dependence on fluence value ϵi for practically all Kinds

High-resolution X-ray spectra of solar flares. VI - Impulsive soft X-ray flares
The Astrophysical Journal, 1982 Doschek et al. (1980) and Feldman et al. (1980) have discussed high-resolution soft X-ray spectra of solar flares. The present investigation is concerned with the characteristics of the impulsive events as observed in soft X rays and the cooling of the flare plasma in terms of energy loss processes.

Height and Energy Evolution of X-Ray Double Sources in a Solar Flare
The Astrophysical JournalIn the standard model, magnetic reconnection at a vertical current sheet above the flare arcade is key to explaining many aspects of solar eruptions. The supra-arcade region is where the vertical current sheet is supposedly located, and X-ray/extreme ...

An interpolation/extrapolation approach to X-ray imaging of solar flares
Inverse Problems and Imaging, 2012 We describe an interpolation/extrapolation procedure that reconstructs X-ray maps of solar flares using as input data sparse samples of the Fourier transform of the radiation flux, named visibilities. The algorithm is based on two steps: in the first step the performance of an interpolation routine is optimized by representing the visibilities ...

A Statistical Study of Soft X-Ray Flares on Solar-type Stars
The Astrophysical JournalThe statistical characteristics of stellar flares at optical bands have received extensive study, but they remain to be studied at soft X-ray bands, in particular for solar-type stars.

Forecasting Solar Energetic Particle (SEP) events with Flare X-ray peak ratios
Journal of Space Weather and Space Climate, 2018 Solar flare X-ray peak fluxes and fluences in the 0.1–0.8 nm band are often used in models to forecast solar energetic particle (SEP) events. Garcia (2004) [Forecasting methods for occurrence and magnitude of proton storms with solar soft X rays, Space ...

Solar Flare X-Ray Measurements and Their Relation to Microwave Bursts [PDF]
Symposium - International Astronomical Union, 1975 This review discusses the available observational material of solar hard X-ray bursts, their interpretation in terms of a model of the source region and their relation with other flash-phase phenomena, in particular the impulsive microwave bursts.
