[en] This paper presents the first study of the properties of the peculiar emission-line star GG Carinae in the ultraviolet wavelength domain. From IUE high resolution spectra, the authors investigate the behaviour of different velocities. From IUE low resolution data, they propose a value of the B-V excess of E[SUB]B-V[/SUB] = 0.52±0.04 (2σ). The continuum of GG Car from the UV to the visible is rather well represented by the theoretical flux of a T[SUB]eff[/SUB] = 18,000K Kurucz standard model atmosphere. The authors investigate also the ultraviolet light curve, which is essentially similar to the one observed in the visible (Gosset et al., 1984, 1985).
