摘要

本文介绍了超新星遗迹(信噪比)G352.7−0.1的Suzaku观测结果。我们在仔细的天空背景估计的基础上进行了光谱分析，发现了1.6 keV的Al发射线，以及之前检测到的Mg、Si、S、Ar、Ca和Fe离子的发射线。0.7-10 keV波段的x射线光谱由具有不同温度和电离时间尺度的双组分电离等离子体模型表示。在此基础上，讨论了x射线等离子体的特性和爆炸类型。

Suzaku spectral analysis of an X-ray emitting plasma in the supernova remnant G352.7−0.1

The results of a Suzaku observation of the supernova remnant (SNR) G352.7−0.1 are presented in this paper. We conducted spectral analysis based on careful sky background estimation and found an emission line from Al at 1.6 keV, in addition to previously detected emission lines from Mg, Si, S, Ar, Ca, and Fe ions. The X-ray spectrum in the 0.7–10 keV band is represented by a two-component ionizing plasma model with different temperatures and ionization timescales. Based on the results, properties of the X-ray emitting plasma and the explosion type are discussed.
