J. ; Koenigsberger, Gloria ; Auer, Lawrence H. Abstract The results of IUE observations of three SMC W-R binary systems at various orbital phases are presented. Selective atmospheric eclipse effects are evident in HD 5980 (WN 4 + O7 I:) and Sk 188 (W04 + O4 V), and are very weak or absent in Sk 108 (WN 3 + O6.5 I:). The difference in heavy-metal content between the SMC and Galactic objects is especially manifest in the lack of atmospheric eclipse effects due to a clustering of Fe V and Fe VI lines in the wavelength range 1360-1470 A in HD 5980.
