| Description | We propose a deep EPIC observation of the highly asymmetric young (< 600 years old) core-collapse (CC) supernova remnant G350.1--0.3, whose spectrum is dominated by iron-rich ejecta expanding at up to 6,000 km/s away from an almost-stationary thermally emitting neutron star (CCO), and for which a very high nickel abundance has been claimed. We shall quantify emission from Ni and Cr, in addition to Fe, to derive constraints on nucleosynthesis in explosive Si-burning regions. We shall also pursue hints of nonthermal emission, search for faint ejecta elsewhere near the CCO, search for the blast wave, and obtain a very deep spectrum of the CCO. G350.1--0.3 may join Cassiopeia A as a major source for understanding of CC processes, and we expect this long observation to have archival value. |

| 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. |
