| Abstract | We propose sensitive XMM observations of the hot gaseous halo of NGC 507 withthe main purpose of unambiguously determining metal abundances. NGC 507 wasselected because it is very bright and exhibits a signature of multi-temperatureemission not only in the core, but also at the outskirts, hence its one of thebest candidates to investigate the issue on the actual metal abundances in hotX-ray halos. The determination of elemental abundances has strong implicationson the supernova II and Ia rates and on the IMF, and consequently on thestructure and history of the hot gaseous halo. With these data, we will alsoinvestigate the central cooling core and determine the nature of the softsources detected at the outskirts with the ROSAT PSPC. |

| 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. |
