UV and X-ray Spectral Lines of FeXXIII Ion for Plasma Diagnostics
We have calculated X-ray and UV spectra of Be-like Fe (FeXXIII) ion in collisional radiative model including all fine-structure transitions among the 2s, 2s2p, 2p, 2snl, and 2pnl levels where n = 3 and 4, adopting data for the collision strengths by Zhang & Sampson (1992) and by Sampson, Goett, & Clark (1984). Some line intensity ratios can be used for the temperature diagnostics. We show 5 rat...

متن کاملX-Ray Spectral Diagnostics of Gamma-Ray Burst Environments.
Recently, detection of discrete features in the X-ray afterglow spectra of GRB 970508 and GRB 970828 was reported. The most natural interpretation of these features is that they are redshifted Fe K emission complexes. The identification of the line emission mechanism has drastic implications for the inferred mass of radiating material and hence the nature of the burst site. X-ray spectroscopy p...
متن کاملX-Ray Spectral Diagnostics Of Activity In Massive Stars
X-rays give direct evidence of instabilities, time-variable structure, and shock heating in the winds of O stars. The observed broad X-ray emission lines provide information about the kinematics of shock-heated wind plasma, enabling us to test wind-shock models. And their shapes provide information about wind absorption, and thus about the wind mass-loss rates. Mass-loss rates determined from X...
متن کاملMorphology and Spectral Behavior of Solar Hard X-ray Sources
Images of 17 solar flares, corresponding to 61 individual X-ray bursts observed in four energy bands (14–23, 23–33, 33–53, and 53–93 keV) by the Hard X-Ray Telescope (HXT) experiment aboard the Yohkoh satellite have been investigated. The images suggest that the angular size of the hard X-ray sources is of the order of 20 arcsec and that they are of three types: single isolated sources (∼ 30%),...
