Variability of C III and Si III lines in the ultraviolet spectral region of the magnetic Bp star a Centauri
Variability ultraviolet spectral region magnetic Centauri
2011/9/30
The variability of twice ionized lines of carbon and silicon in the ultraviolet spectral region of the magnetic Bp star a Centauri is investigated. This study is based on the archival {\it Internation...
Line Identification of the Si Star HD 87240。
Does Si Play a Role in the Formation of Extrasolar Planet Systems?
Planetary systems formation—stars abundances—stars late-type
2009/5/12
With the high signal-to-noise ratio spectra, we obtained Si
abundances of 22 extrasolar planet host stars, and discussed some constraints
on the planet formation. Using our silicon abundance results...

STARK BROADENING PARAMETER TABLES FOR Al XI AND Si XII LINES OF ASTROPHYSICAL INTEREST。
Using a semiclassical approach, we have calculated electron−, proton−,
and He III−impact line widths and shifts for 4 Si XI and 61 Si XIII multiplets
as a function of temperature (...
MEASURED, CALCULATED AND PREDICTED STARK WIDTHS OF THE SINGLY IONIZED C, N, O, F, Ne, Si, P, S, Cl AND Ar SPECTRAL LINES
plasma spectroscopy ionized emitters Ar SPECTRAL LINES
2009/3/18
In order to find reliable Stark width data, needed in plasma spectroscopy,
comparision between the existing measured, calculated and predicted
Stark width values was performed for ten singly ionized...
