Abstract The O abundance is the most important, since it is the most abundant elementexcept H and He, and synthesized only by type II supernovae (SNe). In ellipticalgalaxies, an accumulation of stellar mass loss emit X-rays and therefore, the Oabundance of the X-ray emitting gas reflects the stellar metallicity. Therefore,I propose to observe two elliptical galaxies, NGC 1404 and NGC 4374. anddetermine the O abundance of the gas with the RGS.

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.
