dc.description.abstract	An analysis is made of the high- and low-resolution UV spectra of the hydrogen-poor star HD 30353. The stellar wind profiles of the resonance lines of N V, C V, and Si IV are found to be similar to those observed in Upsilon Sgr. However, HD 30353 shows shortward-shifted profiles also in the ground-level lines of Fe II, in the subordinate multiplet 3 of Mg II, and in the excited lines of Fe III. The results suggest that the shell around HD 30353 may be more extended than that of Upsilon Sgr. The UV excess in the flux shortward of 1800 A suggests that the companion is an early B-type star.	en
