Envelope-stripped, core-collapse SNe (i.e. Type Ibc) have recently enjoyed asurge of interest thanks to their association with Gamma-Ray Bursts (GRBs). Thepeculiar circumstances that enable a small fraction of SNe Ibc to launch arelativistic jet are not understood. Along the same line, the progenitors of SNeIbc and their relation to those of GRBs have yet to be observationallyidentified. Here we propose a continuation of our XMM program, as part of ourmulti-wavelength effort, to enable progress. The primary goals are: (i)Constrain the pre-SN mass-loss history of the progenitor star by sampling theenvironment around H-stripped core-collapse SNe. (ii) Constrain the presence ofengines driving the explosion of the most energetic SNe Ibc that are NOT observationally associated with GRBs.

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.
