Detection of O VIII line emission in the X-ray spectrum of Puppis A.
Abstract
Summary. The detection of the 0 VIII resonance line at 18.97 A in the X-ray spectrum of Puppis A is reported. The observation was carried out by means of a Bragg crystal spectrometer flown on a sounding rocket. Further evidence is obtained for the existence of material at two temperatures in the source. An upper liinit is placed on the gas column density to the source.
