Fig. 2.


Low resolution observed (source plus background) EPIC pn X-ray spectra of the central star (left panel) and the nebula (right panel) in IRAS 00500+6713. The error bars correspond to 3σ. Red histograms show the best-fitting spectral models (see Appendix A and B for details on spectral modeling and the treatment of the background). The prominent emission spectral features are identified at the wavelengths corresponding to the positions of strong emission lines predicted by the apec models for plasma with a chemical composition and temperatures similar to that of IRAS 00500+6713.
