Scientific paper

A description is presented of a high resolution study of the ultraviolet spectrum of the star HD 93206 using the IUE satellite. This star is among those observed at optical wavelengths by Walborn and Hesser (1975) and belongs to the Cr 228 association which lies approximately 15 arcmin south of the peculiar object of Eta Car. This star is part of an on-going UV survey of early-type stars in Carina and other galactic giant H II regions. A detailed line profile fitting analysis is conducted of the I-S ultraviolet resonance lines of C II, C IV, Mg II, Al II, Al III, Si II, Si IV, S II, Cr II, Mn II, Fe II, Ni II, Zn II towards this star. The equivalent widths of all other UV lines observed in the spectrum (1190-3200 A) are also listed and the kinetics and physical properties of the I-S gas are discussed.
