| Abstract | We propose joint NuSTAR-XMM observations of 3C 397, a Type Ia supernova remnant(SNR) likely originating from a near-Chandrasekhar-mass white dwarf in asingle-degenerate progenitor system. Suzaku observations of this SNR detectedstrong emission of the Fe-peak elements (Cr, Mn, Fe, Ni) and indicatedremarkably high mass ratios of Mn/Fe and Ni/Fe. Under the auspices of thisproposal, we will reveal the spatial distribution of these elements to constrainthe properties of the progenitor and the supernova explosion mechanism. NuSTARis particularly suitable for this study, thanks to the highest sensitivity to NiK-alpha emission at 7.6 keV among currently operating X-ray missions. XMM-Newtonprovides a perfect complement to NuSTAR, by enabling clear detection of Cr and Mn lines. |

| 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. |
