摘要：

Using the Max-Planck Millimeter Bolometer Array (MAMBO) at the IRAM 30 m telescope we detected emission at 250 GHz from the Centaur Chariklo (1997 CU26). The observed continuum flux density implies a photometric diameter. of 273 km. The resulting geometric albedo is 0.055, somewhat higher than expected from a comparison with mast of the other few Centaurs and cometary nuclei for which such data are available.
