Observational Characterization of Main-Belt Comet and Candidate Main-Belt Comet Nuclei

Henry H. Hsieh, Marco Micheli, Michael S. P. Kelley +9

We report observations of nine MBCs or candidate MBCs, most of which were obtained when the targets were apparently inactive. We find effective nucleus radii (assuming albedos of p…
