Abstract:
In this work we present the detection of 33 star clusters and 51
candidates in one field of the near by galaxy M 33. 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 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.
