Description:
The IUE was used to obtain high-resolution far-UV spectra (1150-2070 A) of two stars in the 30 Dor H II region in the LMC. Interstellar absorption components are distinguished at +20, +220, +250, and +290 km/s. The +20 km/s component is produced by matter in the Galaxy; the high-velocity components are produced by absorbing gas near or in the LMC. A model of the line-of-sight distribution of the absorbing clouds is developed from the velocity pattern of the observed LMC features. The presence of Si IV, Al III, and C IV ions is discussed.
