标题： The dustiest Post-Main sequence stars in the Magellanic Clouds

摘要： 利用来自“星系演化代理机构”（HERITAGE）麦哲伦云调查的 {\em 赫歇尔} 数据库存档观测数据，我们发现了三十五颗在远红外波段明亮的演化星及恒星终结产物。 这些来源包括二十八个大麦哲伦云（LMC）源和七个小麦哲伦云（SMC）源，它们是从HERITAGE远红外点源目录中的529个演化星候选体中筛选出来的。 我们的源识别方法基于光谱确认、谱能量分布特征、多波长图像的仔细检查，并且包括亮度限制，从而得到一份经过彻底验证的演化星列表。 这些源的亮度范围很广，因此初始质量也有所不同。 我们发现十三颗低至中等质量的演化星，包括渐近巨星分支（AGB）星、后AGB星、行星状星云和一颗共生星。 我们还确定了十颗高质量星，其中包括麦哲伦云中已知的十五颗B[e]星中的四颗、三个被尘埃高度包裹的极端红超巨星、一颗光亮蓝变星、一颗沃尔夫-拉叶星以及两个超新星遗迹。 此外，我们报告了九个之前文献中未描述过的可能的演化星检测。 这些源可能是麦哲伦云中最尘埃丰富的演化星之一。 {\em 赫歇尔}发射可能源于演化星产生的尘埃，也可能来自扫过星际介质（ISM）的物质。 显示英文摘要

摘要： Using observations from the {\em Herschel} Inventory of The Agents of Galaxy Evolution (HERITAGE) survey of the Magellanic Clouds, we have found thirty five evolved stars and stellar end products that are bright in the far-infrared. These twenty eight (LMC) and seven (SMC) sources were selected from the 529 evolved star candidates in the HERITAGE far-infrared point source catalogs. Our source identification method is based on spectral confirmation, spectral energy distribution characteristics, careful examination of the multiwavelength images and includes constraints on the luminosity, resulting in a thoroughly vetted list of evolved stars. These sources span a wide range in luminosity and hence initial mass. We found thirteen low- to intermediate mass evolved stars, including asymptotic giant branch (AGB) stars, post-AGB stars, planetary nebulae and a symbiotic star. We also identify ten high mass stars, including four of the fifteen known B[e] stars in the Magellanic Clouds, three extreme red supergiants which are highly enshrouded by dust, a Luminous Blue Variable, a Wolf-Rayet star and two supernova remnants. Further, we report the detection of nine probable evolved objects which were previously undescribed in the literature. These sources are likely to be among the dustiest evolved objects in the Magellanic Clouds. The {\em Herschel} emission may either be due to dust produced by the evolved star or it may arise from swept-up ISM material.
