| Abstract | Contrary to expectations from current stellar evolutionary models, recentobservations uncovered the ejection of shells of material by massivestars in the years before the supernova (SN) explosion. The physicalmechanism behind the impulsive mass ejection synchronized with the stellarcore-collapse is unclear. Here we propose a coordinated XMM-NuSTAR effortto map the evolution of the broad-band X-ray spectrum of 1 nearby ($d<50$Mpc) strongly interacting SN and enable progress. Our program has theimmediate goal to characterize the medium around strongly interacting SN,which originate from stellar progenitors with the most extreme mass lossbefore 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. |
