Validation of computed extreme ultraviolet emission spectra during solar flares [PDF]
Earth, Planets and Space, 2021 X-rays and extreme ultraviolet (EUV) emissions from solar flares rapidly change the physical composition of the Earth’s thermosphere and ionosphere, thereby causing space weather phenomena such as communication failures.

Muon and Tau Neutrinos Spectra from Solar Flares [PDF]
Chinese Journal of Astronomy and Astrophysics, 2003 Solar neutrino flares and mixing are considered. Most power-full solar flare as the ones occurred on 23th February 1956, September 29th 1989, 28th October and on 2nd-4th November 2003 are sources of cosmic rays, X, gamma and neutrino bursts. These flares

An investigation of Fe XV emission lines in solar flare spectra [PDF]
Astronomy & Astrophysics, 2005 Previously, large discrepancies have been found between theory and observation for Fe XV emission line ratios in solar flare spectra covering the 224-327 A wavelength range, obtained by the Naval Research Laboratory's S082A instrument on board Skylab ...

Investigating the Soft X-Ray Spectra of Solar Flare Onsets
The Astrophysical JournalIn this study, we present the analysis of six solar flare events that occurred in 2022, using new data from the third-generation Miniature X-Ray Solar Spectrometer, also known as the Dual-zone Aperture X-ray Solar Spectrometer (DAXSS).

Analysis of Solar-like X-class Flare on Wolf 359 Observed Simultaneously with TESS and XMM-Newton
The Astrophysical Journal, 2023 We present an analysis of a flare on the Wolf 359 star based on simultaneous observations of Transiting Exoplanet Survey Satellite and XMM-Newton. A stellar flare with energy comparable to an X-class solar flare is analyzed on this star for the first ...

Statistical analysis for EUV dynamic spectra and their impact on the ionosphere during solar flares
Earth, Planets and Space, 2023 The X-rays and extreme ultraviolet (EUV) emitted during solar flares can rapidly change the physical composition of Earth’s ionosphere, causing space weather phenomena.

Solar flares as proxy for the young Sun: satellite observed thermosphere response to an X17.2 flare of Earth's upper atmosphere [PDF]
Annales Geophysicae, 2012 We analyzed the measured thermospheric response of an extreme solar X17.2 flare that irradiated the Earth's upper atmosphere during the so-called Halloween events in late October/early November 2003.

The Transition Region of Solar Flare Loops
The Astrophysical Journal, 2023 The transition region between the Sun’s corona and chromosphere is important to the mass and energy transfer from the lower atmosphere to the corona; consequently, this region has been studied intensely with ultraviolet and extreme ultraviolet (EUV ...
