Abstract
Using archival Far Ultraviolet Spectroscopic Explorer (FUSE) and Hubble Space Telescope (HST) data, we have assembled a survey of eight sight lines through high-velocity cloud Complex C. We find that the metallicity of the complex, based on [OI/HI], ranges from 0.1Z–0.25 solar. These data indicate that parts of the cloud have a higher metallicity than previously thought and that Complex C may represent a mixture of “Galactic fountain” gas with infalling low-metallicity gas. Further, we find that the abundances of O, Si, and S are enhanced relative to N and Fe, suggesting that the bulk of the metals in Complex C were produced by Type II supernovae.
