Abstract	We propose a 200 ks XMM-Newton observation of the Fe-rich knot in the Type Iasupernova remnant of Kepler to confirm that the explosion originated from anear-Chandrasekhar-mass white dwarf (WD). Previous observations by Chandra haverevealed an Fe-rich ejecta knot within the SNR moving at nearly the freeexpansion speed. The current spectrum of the knot shows strong emission linesfrom Fe-peak elements (Cr, Mn, Ni), pointing to an origin in the deepest layerof a near-Chandrasekhar-mass WD. However, due to high background in the Chandradata, it is difficult to claim a significant detection of the Ni line, which iskey to determining the burning regime. Thanks to low background, highsensitivity in the Ni band, only the XMM-Newton can resolve this important issue in SN Ia physics.

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.
