|Title||X-ray Spectrometry of SN1987A|
|Author||Dr Frank Haberl|
|Description||Between 2007 and 2017, our yearly XMM-Newton monitoring of SN1987A yielded EPIC and RGS spectra of unprecedented quality. The fluxes and broadening of the numerous emission lines provide information on the evolution of the X-ray emitting plasma and its dynamics. The soft X-ray light curve shows a mild flattening after 2006 and a flux decrease since 2014. To further monitor the evolution of the X-ray flux and to follow the expected turn-over we propose to continue our monitoring. This will allow us to further study the time evolution of the shock conditions and abundance profiles. At high energies EPIC-pn can help to clarify the extremely low observed Fe abundance by following the evolution of the detected Fe-K line.|

|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.
