Scientific paper

The authors have derived abundances in intermediate-velocity clouds toward SN 1987A, using high-resolution data from the IUE. For the 70 km s-1 cloud, abundances are close to their values in the Sun and a galactic halo origin is proposed for the cloud. The two other features, at 129 and 171 km s-1, have mean abundances of -0.59±0.15 dex and -0.46±0.15 dex relative to solar values and are similar to LMC abundances derived from ionized gas. These features probably arise in gas associated with the LMC and not our Galaxy.
