Abstract	The metallicity of hot gas in E/S0 galaxies is known to vary widely, in thesense that galaxies with only small amounts of hot gas often have very low hotgas metallicities. One solution is that what little hot gas X-ray faint systemshave has been diluted by pristine hydrogen gas in the vicinity of the galaxy.There is a growing body of evidence suggesting that some early-type galaxiesharbor sizable large-scale HI halos, presumably left over from the epoch ofgalaxy formation. If this pristine HI is accreted, the existing hot gas in thegalaxy will be diluted. We propose to test this by measuring the metallicitiesof a sample of X- ray faint galaxies with a range of HI-to-hot gas ratios. Ifthe dilution hypothesis is correct, galaxies with more HI will have lower hot gas metallicities.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
