Abstract GT- Metals injected into the hot gas in galaxy groups preserve a recordof the history of chemical evolution and gas ejection for theirconstituent galaxies. The ratio of Fe to alpha elements as a functionof radius will constrain the history of SNI and SNII activity, andemission from individual group galaxies will constrain the strippingof gas and dark halos. We have selected a sample consisting of the twomost X-ray luminous Hickson compact groups, and a loose group ofcomparable X-ray brightness. Comparison between these systems willclarify the nature of compact groups and the dynamical evolution ofall groups.

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.
