J/A+A/444/831       New star clusters in M33                  (Bedin+, 2005)

Star cluster detection with WFC/ACS in M33. 33 new clusters and 51 candidates. Bedin L.R., Piotto G., Baume G., Momany Y., Carraro G., Anderson J., Messineo M., Ortolani S. <Astron. Astrophys., 444, 831-836 (2005)> =2005A&A...444..831B

This study is based on WFC/ACS images available from the HST archive. Thanks to the high resolving power, we were able to confirm that two candidates previously indicated by Christian & Schommer (1982ApJS...49..405C) are indeed star clusters. We list the main properties for the star clusters (and candidates), along with some peculiar objects, such as background galaxies and possible HII regions. File Summary:
