X-ray and EUV spectroscopy of various astrophysical and laboratory plasmas -- Collisional, photoionization and charge-exchange plasmas
G. Y. Liang, F. Li, F. L. Wang +3
Several laboratory facilities were used to benchmark theoretical spectral models those extensively used by astronomical communities. However there are still many differences betwee…
R-matrix electron-impact excitation data for astrophysically abundant sulphur ions
G. Y. Liang, N. R. Badnell, G. Zhao +2
We present results for the electron-impact excitation of highly-charged sulphur ions (S8+ - S11+) obtained using the intermediate-coupling frame transformation R-matrix approach. A…
Electron density diagnostic for hot plasmas in coronal regime by using B-like ions
Guiyun Liang, Gang Zhao
Line ratio of transition lines in boron-like spectra of Si X, S XII, Ar XIV and Fe XXII has been investigated. Collisional-radiative model calculations reveal that the line…
Soft X-ray emissions of highly charged Si VII--Si XII in cool star--Procyon
G. Y. Liang, G. Zhao
Different observation data for cool star--Procyon (Obs\_IDs of 63, 1461 and 1224) available from {\it Chandra Data Public Archive} were co-added and analyzed. Emissivities of emiss…
Electron density diagnostic potential of Ar XIV soft X-ray emission lines
G. Y. Liang, G. Zhao, J. L. Zeng +1
Theoretical electron density-sensitive line ratios of Ar XIV soft X-ray emission lines are presented. We found that these line ratios are sensitive to electron density…
Determinations of temperature and density for solar-like Stars using Si XI soft X-ray emission lines
G. Y. Liang, G. Zhao
We study temperature and density sensitivities of ratios of Si XI soft X-ray emission lines, in the wavelength range of 43--54Å. The typical temperature of the formation of the ana…
