Scientific paper

We propose to observe the isolated hard X-ray sources discovered recently with XMM-Newton in the region of the interaction of supernova remnant IC 443 with a molecular cloud. Some of the detected hard X-ray sources have features that were predicted for a new class of X-ray sources - fast isolated supernova ejecta fragments in molecular clouds. A real identification requires subarcsecond resolution available only with CXO. We will perform a detailed imaging spectroscopy of the sources. The analysis of spatially resolved images and spectra will make it possible to determine the abundances of the fragments ejected from the internal layers of the supernova. The study would provide the first identification of the isolated sources with new constrains for stellar nucleosynthesis.
