The high resolution spectrum of the VV Cep star KQ Pup observed with the IUE satellite during 1979 and 1980 is summarized. More than 600 lines have been identified between 1190 and 3228 A. Two main line systems are present, a broad absorption line system, which includes high ionization lines from N V, C IV, Si IV and Al III, and narrow P Cygni lines of neutral and singly ionized elements, mostly of Fe II. The Mg II resonance doublet is very prominent in emission with a sharp central absorption. The intensity of the absorption and emission components of the Fe II lines is different according to the excitation potential, transition strength and wavelength. Fe II emission lines with E.P. up to 13 eV are present. Several Fe II lines, were identified using the new Kurucz's computations.

Abstract
The high resolution spectrum of the VV Cep star KQ Pup observed with the IUE satellite during 1979 and 1980 is summarized. More than 600 lines have been identified between 1190 and 3228 A. Two main line systems are present, a broad absorption line system, which includes high ionization lines from N V, C IV, Si IV and Al III, and narrow P Cygni lines of neutral and singly ionized elements, mostly of Fe II. The Mg II resonance doublet is very prominent in emission with a sharp central absorption. The intensity of the absorption and emission components of the Fe II lines is different according to the excitation potential, transition strength and wavelength. Fe II emission lines with E.P. up to 13 eV are present. Several Fe II lines, were identified using the new Kurucz's computations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
