X-ray Spectrometry of SN1987A

Since Jan. 2007, our yearly XMMNewton 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 Xray emitting plasma and its dynamics. The soft Xray light curve shows a significant flatteningafter 2006. To further monitor the turnover we propose to continue ourXMMNewton monitoring. This will allow us to further study the time evolution ofthe shock conditions and abundance profiles. At high energies EPICpn can helpto clarify the extremely low observed Fe abundance by following the evolution ofthe detected FeK 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? truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
