Scientific paper

We present high-resolution X-ray spectra of massive stars Zeta Puppis and Eta Carinae obtained with the Reflection Grating Spectrometer (RGS) onboard the XMM/Newton observatory. The spectrum of Zeta Puppis has many emission lines, including bright, broad hydrogenic and helium-like lines from oxygen and nitrogen. Analysis of these lines indicates a plasma density of at least 1010 {cm}-3. The spectrum of Eta Carinae is dominated by the bright hydrogenic nitrogen line. We will present the analysis of the spectra and discuss implications.
