We present high dispersion HST GHRS UV spectroscopic observations of 8 H II galaxies covering a wide range of metallicities and physical properties. We have found Lyα emission in 4 galaxies with blueshifted absorption features, leading to P Cygni like profiles in 3 of them. In all these objects the O I and Si II absorption lines are also blueshifted with respect to the ionized gas, indicating t...

We have collected one-dimensional raster-scan observations of the active star-forming region Sharpless 171 (S171), a typical H ii region-molecular cloud complex, with the three spectrometers (LWS, SWS, and PHT-S) on board ISO. We have detected 8 far-infrared fine-structure lines, [O iii] 52 µm, [N iii] 57 µm, [O i] 63 µm, [O iii] 88 µm, [N ii] 122 µm, [O i] 146 µm, [C ii] 158 µm, and [Si ii] 35...
