Abstract

We present a study of the thermal properties of about 70 trans-Neptunian objects (TNOs) and Centaurs observed with Herschel Space Observatory [8] (either PACS or PACS and SPIRE) and Spitzer Space Telescope [12] (MIPS). We apply radiometric modeling techniques (NEATM [2]) to the measured fluxes to derive diameter, albedo and the beaming factor (η). The latter parameter is a proxy for the combined effects of surface thermal properties (thermal inertia), surface roughness, and rotation properties. We will examine the results and search for trends in the inferred η values with several parameters, including heliocentric distance, albedo, and rotational properties.
