Spectral analysis of the Galactic supernova remnant Kesteven 69 with Suzaku.
YAMAUCHI S. and PANNUTI T.G.
Abstract (from CDS):
The results of a Suzaku observation of the supernova remnant (SNR) Kesteven 69 = G21.8-0.6 are presented. To estimate the sky background precisely, we conducted a simultaneous fit of the source region spectrum with the background region spectrum and found that the SNR spectrum is well represented by a two-component ionizing plasma model composed of a low-temperature plasma at kTe = 0.80 ± 0.11 keV and a high-temperature plasma at kTe = 1.5 ± 0.4 keV. The existence of a low-ionized Fe K line at 6.49 ± 0.07 keV was confirmed. The center energy of the line is consistent with those of type Ia SNRs.
