Scientific paper

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