Abstract We propose to observe the two groups of galaxies NGC 5044 and NGC 5813 each with130 ks exposure time. We will combine these data with archival data of threeother groups. The RGS spectra will reveal accurate abundances of nitrogen andcarbon, key elements produced both by massive stars and intermediate mass AGBstars. The EPIC spectra will give accurate abundances of all elements heavierthan oxygen. The combined spectra allow us to measure the contributions to themetal enrichment by each of the individual categories: intermediate and low massstars, core collapse supernovae and type Ia supernovae. In addition, we willmeasure the spatial distribution of these elements.

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.
