综合超新星遗迹视线内恒星的光度、光谱和天体测量信息，研究了32个银河系超新星遗迹的距离和位置。恒星大气参数来自斯隆数字巡天− DR 14/阿帕奇点天文台星系演化实验和大天区多目标光纤光谱望远镜− DR 5/LEGUE光谱巡天。从光学到红外的多波段测光，收集自盖亚，APASS，Pan-STARRS 1，2微米全天巡天和宽视场红外巡天探测器巡天。通过校准单个恒星的盖亚距离，32个SNRs中的15个的距离可以很好地从它们产生的消光和与分子云的关联中确定。推导了三种信噪比下的距离上限。计算了32个信噪比的色余比，并用一个简单的尘埃模型拟合了它们随波段的变化。推断的尘埃颗粒大小分布分叉：虽然石墨颗粒的大小与平均星际介质尘埃相当，但硅酸盐颗粒通常更大。沿着这条路，从130万颗恒星样本中导出了银河系从光学到近红外的平均消光定律，发现与CCM 89定律一致。
By combining the photometric, spectroscopic, and astrometric information of the stars in the sightline of supernova remnants (SNRs), the distances to and the extinctions of 32 Galactic SNRs are investigated. The stellar atmospheric parameters are from the Sloan Digital Sky Survey−DR14/Apache Point Observatory Galaxy Evolution Experiment and Large sky Area Multi-Object fiber Spectroscopic Telescope−DR5/LEGUE spectroscopic surveys. The multiband photometry, from optical to infrared, are collected from the Gaia, APASS, Pan-STARRS1, Two Micron All Sky Survey, and Wide-field Infrared Survey Explorer surveys. With the calibrated Gaia distances of individual stars, the distances to 15 of 32 SNRs are well determined from their produced extinction and association with molecular clouds. The upper limits of distance are derived for three SNRs. The color excess ratios of 32 SNRs are calculated, and their variation with wavebands is fitted by a simple dust model. The inferred dust grain size distribution bifurcates: while the graphite grains have comparable size to the average interstellar medium dust, the silicate grains are generally larger. Along the way, the average extinction law from optical to near-infrared of the Milky Way is derived from the 1.3-million-star sample and found to agree with the CCM89 law with .
