| Abstract | The X-ray luminosity of SN1987A rapidly increased over the last four years, suchthat in a single 100 ks XMM-Newton obervation spectra can be taken withexcellent counting statistics up to energies of 10 keV and more. In reference toour accepted 100 ksec AO5 observation another observation ~1 year later willallow to study the time evolution of the shock conditions and abundance profilesof N, O, Fe and Ne with RGS. At high energies EPIC-pn can help to clarify theextremely low Fe abundance of 0.04, observed so far. Is the Fe completelyswallowed by the central compact object or is the emission from the innersections of the progenitor star still absorbed? Because of the high number ofcounts a sensitive search for pulses from the pulsar limited to high energy photons will be possible. |

| 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. |
