We propose to investigate the intrinsic properties of the hotinterstellar-medium in early-type galaxies. To this end we have chosen a wellselected sample of isolated, optically similar, nearby, elliptical galaxies tominimize the influence of external factors such as the presence of a group orluminous masses. Three objects recently published cover the full range of LX:LBscatter observed in larger, heterogeneous samples. A fourth one, observedsubsequently, has low luminosity X-ray emission. With this proposal we requestfour additional objects that will complete the small, but homogeneous sample ofbright Ellipticals.

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.
