5-14 Μm Spitzer spectra of Themis family asteroids
We present 5-14 μm spectra of 8 Themis family asteroids observed with Spitzer. The diameter and geometric albedo are determined using the NEATM model. Their emissivity spectra is studied in order to determine if they exhibit an emission plateau at about 9 to 12 μm as observed in other primitive asteroids of the outer belt, attributed to fine
