Description Recent work find evidence of an increase of the Iron abundance in clusters with temperatures below 5 keV, up to a value about 3 times larger than that typical of very hot clusters. This behaviour is likely related to fundamental processes of metal production and release in low--temperature objects. From spatially-unresolved ASCA metallicity measurements, we select 9 clusters with Z>0.6 Z_odot . For none of these, apart from one, is possibile to recover the metal abundance profile with the available data. We aim to make proper use of XMM-Newton to resolve spatially the metal distribution in the central regions of the 3 brightest objects never resolved spatially before.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
