| Abstract | Tychos SNR provides a pristine laboratory of what remains four and a halfcenturies after a Type Ia SN. We propose an observation of the southeast portionto observe two bright ejecta knots of interest. Both are Fe-rich, while onecontains significant Si as well. RGS observations of these knots will reveal thenumerous Fe L-shell and Si lines present, from which we can determine the stateof the reverse-shocked ejecta, the thermal line broadening present, search foroxygen, an indicator of a double-degenerate supernova, and possibly measure thetime evolution of the Fe K$alpha$ line at 6.5 keV, something never before done.Observations such as these will be crucial for understanding the physics ofshocked plasmas in preparation for the next generation of high spectral resolution X-ray observatories. |

| 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. |
