Aims. We report on the thermal properties and composition of asteroid (2867) Steins derived from an analysis of new Spitzer Space Telescope (SST) observations performed in March 2008, in addition to previously published SST observations performed in November 2005. Methods. We consider the three-dimensional shape model and photometric properties derived from OSIRIS images obtained during the flyby of the Rosetta spacecraft in September 2008, which we combine with a thermal model to properly interpret the observed SST thermal light curve and spectral energy distributions. Results. We obtain a thermal inertia of 100 ± 50 J K-1 m-2 s−1/2 and a beaming factor (roughness) in the range 0.7–1.0. We confirm that the infrared emissi...
