The flaring and quiescent components of the solar corona

, 2008
The solar corona is a template to understand stellar activity. The Sun is a moderately active star, and its corona differs from active stars: active stellar coronae have a double-peaked EM(T) with the hot peak at 8-20 MK, while the non flaring solar ...

Detecting the Sun’s active region using image processing techniques

Physical Sciences and Technology, 2021
The term ‘space weather’ refers to adverse conditions on the Sun that could affect the structures of space or terrestrial technology and risk human health or life. Flares produce effects that span the electromagnetic spectrum.

Solar Flare Ion Temperatures

The Astrophysical Journal Letters
Abstract This Letter proposes that the ion temperature is several times the local electron temperature in the hot onset phase and in the above-the-loop region of solar flares. The Letter considers: the evidence of spectral line Doppler widths (“nonthermal” broadening); evidence for “universal” ion and electron temperature increase ...

The HESP (High Energy Solar Physics) project [PDF]

A project for space observations of solar flares for the coming solar maximum phase is briefly described. The main objective is to make a comprehensive study of high energy phenomena of flares through simultaneous imagings in both hard and soft X-rays ...

The Occurrence of Powerful Flares Stronger than X10 Class in Solar Cycles

The Astrophysical Journal Letters
Solar flares stronger than X10 (S-flares,  >X10) are the highest-class flares that significantly impact on the Sun's evolution and space weather. Based on observations of Geostationary Orbiting Environmental Satellites at soft X-ray wavelength and the ...

Solar flare neutrinos

Il Nuovo Cimento C, 1991
The theory of high-energy neutrinos generation in the solar atmosphere during the flares is developed. A possible effect in different neutrino detectors is discussed.

Solar flares: An overview

Advances in Space Research, 1992
This is a survey of solar phenomena and physical models that may be useful for improving forecasts of solar flares and proton storms in interplanetary space. Knowledge of the physical processes that accelerate protons has advanced because of gamma-ray and X-ray observations from the Solar Maximum Mission telescopes.
