Abstract | Since Jan. 2007, our yearly XMM-Newton monitoring of SN 1987A yields EPIC andRGS spectra of unprecedented quality. The fluxes and broadening of the numerousemission lines provide information on the evolution of the X-ray emitting plas-ma and its dynamics. The soft X-ray light curve shows a significant flatteningafter 2006. To further monitor the turn-over we propose to continue ourXMM-Newton monitoring. This will allow us to further study the time evolution ofthe shock conditions and abundance profiles. At high energies EPIC-pn can helpto clarify the extremely low observed Fe abundance by following the evolution ofthe detected Fe-K line. Is most of the Fe swallowed by the central compactobject or is the emission from the inner sections of the progenitor star still absorbed? |

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. |
