摘要

摘要介绍了超新星遗迹(SNR) Kesteven 69 = G21.8−0.6的Suzaku观测结果。为了准确估计天空背景,我们将源区光谱与背景区光谱进行了同步拟合,发现由低温等离子体(kTe = 0.80±0.11 keV)和高温等离子体(kTe = 1.5±0.4 keV)组成的双组分电离等离子体模型可以很好地代表信噪比谱。证实了在6.49±0.07 keV下存在低电离Fe - K线。该线的中心能量与Ia型信噪比一致。

Spectral analysis of the Galactic supernova remnant Kesteven 69 with Suzaku
Abstract 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.
