Contrary to expectations from current stellar evolutionary models, recentobservations uncovered the ejection of shells of material by massive stars inthe years before the supernova (SN) explosion. The physical mechanism behind theimpulsive mass ejection synchronized with the stellar core-collapse is unclear.Here we propose a coordinated XMM-NuSTAR effort to map the evolution of thebroad-band X-ray spectrum of 1 nearby (d<50 Mpc) strongly interacting SN andenable progress. Our program has the immediate goal to characterize the mediumaround strongly interacting SN, which originate from stellar progenitors withthe most extreme mass loss before explosion.

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.
