摘要:

我们介绍了银河系超新星遗迹(SNR)G355.6-0.0观测朱雀。我们将ASCA探测到的漫射发射分解为两个物体,G355.6-0.0和一个点状源,朱雀J173530-3236。来自G355.6-0.0的X射线发射在射电壳层内呈现出中心填充的形态。X射线谱很好地代表了一个薄的热等离子体模型与增强的金属丰度。G355.6-0.0的空间和光谱特性表明它属于混合形态信噪比。约6 x 10^{22} cm^{-2}的NH值支持G355.6-0.0是远距离SNR。朱雀J173530-3236的硬X射线谱中有一条强的Fe发射线,与激变变星的发射线相似。约3 x 10^{22} cm^{-2}的NH值小于G355.6-0.0的NH值,因此朱雀J173530-3236位于G355.6-0.0的近侧。

英文摘要:

We present results of the Galactic supernova remnant (SNR) G355.6-0.0 observed with Suzaku. We resolved the diffuse emission detected with ASCA into two objects, G355.6-0.0 and a point-like source, Suzaku J173530-3236. The X-ray emission from G355.6-0.0 exhibits a center-filled morphology within the radio shell. The X-ray spectrum is well represented by a thin thermal plasma model with enhanced metal abundances. The spatial and spectral properties imply that G355.6-0.0 is a member of the mixed-morphology SNRs. The NH value of ~ 6 x 10^{22} cm^{-2} supports that G355.6-0.0 is a distant SNR. Suzaku J173530-3236 exhibits a hard X-ray spectrum with a strong Fe emission line, similar to those of cataclysmic variables. The NH value of ~ 3 x 10^{22} cm^{-2} is smaller than that of G355.6-0.0, and hence Suzaku J173530-3236 is located at the near side of G355.6-0.0.
