摘要：

The detection of the O VIII resonance line at 18.97 Å 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 limit is placed on the gas column density to the source. © Royal Astronomical Society.
