Abstract (from CDS):

We present photometric and spectroscopic observations of one Trans-Neptunian Object (TNO 47171 1999 TC36) and one Centaur (Thereus also named 32532 2001 PT13). Near-infrared data were acquired with the ISAAC instrument at one of the 8m telecopes of the Very Large Telescope (VLT, ESO-Cerro Paranal, Chile), while visible data were obtained with the EFOSC2 instrument on the 3.6m telescope of La Silla (ESO, Chile). These observations were performed to search for rotational variations for both targets. Water ice has been confirmed on both objects. The surface composition models of the targets are presented and discussed, and are also compared to previous observations available in the literature.
