| Description | 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 a single-degenerate progenitor system. Suzaku observations of this SNR detected strong emission of the Fe-peak elements (Cr, Mn, Fe, Ni) and indicated remarkably high mass ratios of Mn-Fe and Ni-Fe. Under the auspices of this proposal, we will reveal the spatial distribution of these elements to constrain the properties of the progenitor and the supernova explosion mechanism. NuSTAR is particularly suitable for this study, thanks to the highest sensitivity to Ni K-alpha emission at 7.6 keV among currently operating X-ray missions. XMM-Newton provides a perfect complement to NuSTAR, by enabling clear detection of Cr and Mn lines. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
