摘要
超新星遗迹是超新星爆炸的产物，通常在 X 射线波段观测到。然而，在对脉冲星和脉冲星风星云进行初步搜索后，银河系超新星残余物 G28.8+1.5 的弥散发射却被忽视了。本文利用XMM-牛顿的档案数据进行了背景减缩成像和空间分辨光谱分析，揭示了弥散发射的前所未有的细节，提供了距离和年龄的最新估计值。研究首次揭示了铁元素过剩的现象，并推测其祖先为 9-15 M⊙。这些发现完善了我们对G28.8+1.5的理解，有助于更广泛地理解银河系超新星残余家族。
A Diamond Ring in X-Ray: Investigating the Diffuse Emission of Supernova Remnant G28.8+1.5
Supernova remnants are products of supernova explosions, which are usually observed in the X-ray band. However, the diffuse emission from the galactic supernova remnant G28.8+1.5 has been overlooked following initial searches for pulsars and pulsar wind nebulae. This paper presents background-subtracted imaging and spatial-resolved spectral analyses using archival XMM-Newton data to reveal unprecedented details of the diffuse emission, providing updated estimates of distance and age. For the first time, an iron overabundance is revealed and the progenitor is suggested to be 9–15 M⊙. These findings refine our understanding of G28.8+1.5 and contribute to a broader comprehension of the Galactic supernova remnant family.
