Query: TNOs are Cool! A Survey of the transneptunian Region XV. Physical
  characteristics of 23 resonant transneptunian and scattered disk objects   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.
