900-1200 Å interstellar extinction in the galaxy, Large Magellanic Cloud, and Small Magellanic Cloud.

HUTCHINGS J.B. and GIASSON J.

Abstract (from CDS):

We have derived far-ultraviolet extinction curves for stars in the Galaxy, LMC, and SMC from spectra of pairs of stars observed with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, matched in spectral type and with different amounts of reddening. The stars were observed for other FUSE programs and were not selected for large reddening. Thus, uncertainties in the derived extinction curves depend on the photometric data. In the case of strongly reddened stars from the Galaxy, the strong H2 absorption at the shortest wavelengths is an additional complication. These initial results indicate that there is a family of extinction curves that rise strongly to the Lyman limit and extend the related extinction curves from longer wavelengths.
