دراسة طيفية للثنائي الكسوفي Vsge

Abstract EN

The aim of study is analysis of spectral observations of the binary system Vsge , which obtained by IUE satellite in the ultraviolet region from ( 1100 – 2000 ) Å with two different phases .

the absorption line profile of ( SiII = 1206 Å ) and the emission lines in profiles of ( SiIV = 1402.77 Å ) and ( CIV = 1550 Å ) which used in the study .

These lines are completely determined , characterized and sharp according to the continuous spectral base .

the equivalent width for each mode measured in both phases .

Also , the constants of Zirin equation are computed in terms of the width in the midway of the peak of the effective wavelength [ FWHM ] .
