摘要：
We present the results from the Suzaku observations of SS Cyg in quiescence and outburst carried out in November, 2005. Owing to an excellent energy-resolving power of the XIS, we resolved the 6.4 keV iron K alpha line into a narrow component and a broad tail in quiescence, which probably originate from the white dwarf and inner accretion disk, respectively. The 6.4 keV line in outburst is dominated by an extremely broad component. These 6.4 keV line features are first recognized by Suzaku this time. Using the iron abundance of 0.30 +/- 0.03Z(circle dot) obtained from our analysis of the outburst spectra, we set the upper limit of the radial extent of the BL to be < 0.15R(WD) in quiescence.
