Abstract

The goal of this work is to determine the physical characteristics of resonant, detached and scattered disk objects in the transneptunian region, observed mainly in the framework of the "TNOs are Cool!" Herschel Open Time Key Program. Based on thermal emission measurements with the Herschel/PACS and Spitzer/MIPS instruments we determine size, albedo, and surface thermal properties for 23 objects using radiometric modelling techniques. This is the first analysis in which the physical properties of objects in the outer resonances are determined for a notable sample. In addition to the results for individual objects, we have compared these characteristics with the bulk properties of other populations of the transneptunian region. The newly analyzed objects show a large variety of beaming factors, indicating a diversity of thermal properties, and in general, they follow the albedo-colour clustering identified earlier for Kuiper belt objects and Centaurs, further strengthening the evidence for a compositional discontinuity in the young Solar System.
TNOs很酷!跨州地区调查十五。23个跨海王星和散射盘状天体的物理特性
这项工作的目标是确定跨海王星区域共振、分离和分散的盘状物体的物理特征,主要是在“TNOs很酷!”的框架下观察到的。赫歇尔打开时间钥匙程序。基于赫歇尔/PACS和斯皮策/MIPS仪器的热发射测量,我们使用辐射建模技术确定了23个物体的尺寸、反照率和表面热性能。这是第一次对一个显著样本确定外共振中物体的物理性质的分析。除了个别物体的结果外,我们还将这些特征与跨海王星地区其他种群的总体特性进行了比较。新分析的天体显示出大量不同的光束因子,表明热特性的多样性,总的来说,它们遵循先前在柯伊伯带天体和半人马座天体中发现的反照颜色聚类,进一步加强了年轻太阳系成分不连续性的证据。
