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…
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…
Coronal density diagnostics with Si X: CHANDRA/LETGS observations of Procyon, Cen A$&$B, Capella and Eri
G. Y. Liang, G. Zhao, J. R. Shi
Electron density diagnostics based on a line intensity ratio of Si X are applied to the X-ray spectra of Procyon, Cen A$&$B, Capella and Eri measured with the Low Energy Tr…
