Far-UV Spectroscopy: An Unexplored Frontier

A three year, NASA mission, successfully launched at 15:44:00 GMT on 24 June 1999 covering the far-UV region (905-1195Å) at high spectral resolution. 10,000 times more sensitive than Copernicus (1970s), allowing amongst other things accurate measurements of deuterium in a variety of environments.

The only UK Science Team involvement is at UCL for the hot star programme. A large sample of OB and WR stars have been selected in Galaxy and Magellanic Clouds, covering all spectral types and luminosity classes (see below). Observations will allow a direct determination of mass-loss versus metallicity through stellar wind resonance lines in the far-UV, necessary for an improved understanding of high redshift primordial galaxies.
