Özet:

 

SS Cyg is a dwarf nova binary star that undergoes frequent  large amplitude outburst within a period of 40 days.  SS Cyg was  observed with the Chandra x-ray telescope in quiescence on 2000 August  24, and near the peak and early decline of a narrow outburst on 2000  September 12 and 14 (exposures of 47 and 96 ks).  The spectrum of the  source shows strong emission lines of O VII and O VIII in all three  observations.  These lines, we note, originate from the boundary  layer.
