cds-question@unistra.frglobular-star-clustersgalaxiesphotometryWe have carried out a survey of compact star clusters (apparent size <~3") in the southwest part of the M31 galaxy, based on the high-resolution Suprime-Cam images (17.5'x28.5'), covering ~15% of the deprojected galaxy disk area. The UBVRI photometry of 285 cluster candidates (V<~20.5mag) was performed using frames of the Local Group Galaxies Survey. The final sample, containing 238 high probability star cluster candidates (typical half-light radius r_h_~1.5pc), was selected by specifying a lower limit of r_h_>~0.15" (>~0.6pc). We derived cluster parameters based on the photometric data and multiband images by employing simple stellar population models. The clusters have a wide range of ages from ~5Myr (young objects associated with 24um and/or H{alpha} emission) to ~10Gyr (globular cluster candidates), and possess mass in a range of 3.0<~log(m/m_{sun}_)<~4.3 peaking at m~4000m_{sun}_. Typical age of these intermediate-mass clusters is in the range of 30Myr<~t<~3Gyr, with a prominent peak at ~70Myr. These findings suggest a rich intermediate-mass star cluster population in M31, which appears to be scarce in the Milky Way galaxy.2009ApJ...703.1872Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/703/1872CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/subaru : Log of Subaru Prime Focus Camera Exposures (ADAC NAOJ, 2007)J/PASP/122/745 : HST WFPC2 star clusters in M31.
