Diagnosing Solar Plasmas from EUV and X-Ray Emission Lines [PDF]
Symposium - International Astronomical Union, 1990 The electron density and temperature measurement of solar plasmas from EUV and X-ray emission lines have been briefly discussed. Diagnostic EUV line ratios from MgVI ion and X-ray line ratios from MgVIII and SiX ions have been presented. A brief account of the general methodology for diagnostics of inhomogeneous structures has also been given.

Solar Flare Doppler Blueshifted Soft X‐Ray Emission and Hard X‐Ray Bursts
The Astrophysical Journal, 2001 Hard X-ray emission and the dynamics of soft X-ray emitting plasma are among the most immediate manifestations of solar flare energy release. To understand better the early impulsive phase of solar flare energy release, we have examined Ca XIX and Fe XXV soft X-ray resonance line spectra that exhibit strong blue-wing asymmetries from 32 flares.

Relation of Microwave Emission to X-Ray Emission from Solar Flares [PDF]
Symposium - International Astronomical Union, 1975 Recent observations of impulsive microwave and hard X-ray emissions during the early phase of the flares are briefly reviewed in order to deduce the dynamics of energetic electrons consistently from two view points of the microwaves and X-rays. An emphasis is put on the necessity of distinction between temporal and spatial variations so far confused in

Spatially Resolved Oscillations of a Flare Looptop X-Ray Source
The Astrophysical Journal LettersThe looptop region in solar flares is a crucial site to understand the physical processes of magnetic reconnection and particle acceleration. Here, we report novel details of a flare looptop X-ray source that is associated with electron acceleration. The

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).
