2001A&A...379..107T XMM-Newton observations of the cluster of galaxies Abell 496 Measurements of the elemental abundances in the intracluster medium T. Tamura, J. A. M. Bleeker, J. S. Kaastra, C. Ferrigno and S. Molendi SRON National Institute for Space Research, Sorbonnelaan 2, 3584 CA Utrecht, The Netherlands IFC Milan, 20133 Milano, Italy Received 16 May 2001/Accepted 13 September 2001 Abstract. The results from XMM-Newton observations of the relaxed cluster of galaxies Abell 496 are presented. The spatially-resolved X-ray spectra taken by the European Photon Imaging Cameras show a temperature drop and a Fe abundance increase in the intra-cluster medium (ICM) towards the cD galaxy at the cluster center. The abundances of Si and S also show a central enhancement. High resolution soft X-ray spectra obtained with the Reflection Grating Spectrometers provides a strong constraint on the temperature structure in the central cool plasma. Furthermore, the O abundance at the cluster core is accurately measured based on the O VIII Ly{alpha} line detected with the RGS. Contrary to the Si, S, and Fe abundances, the O abundance is radially constant over the cluster.
