By observing the X-ray emission properties of young supernovae (SNe), physicalkey parameters such as the circumstellar matter (CSM) density, the mass-lossrate of the progenitor, and the temperature of the outgoing and reverse shockcan be studied as a function of time. We propose follow-up observations of thebrightest known X-ray emitting SNe (1978K, 1979C, 2004dj) to study thetemperature evolution, establish the physical parameters of the ambient CSM outto radii of E18cm from the sites of the explosions, and to monitor the mass-lossrates over 10^4 years in the progenitors stellar wind history. Studying thesekey parameters as a function of time has never been done before.

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.
