J/A+A/397/177       IR star clusters and stellar groups catalog    (Bica+, 2003)

A catalogue of infrared star clusters and stellar groups. Bica, E., Dutra C.M., Barbuy B. <Astron. Astrophys. 397, 177 (2003)> =2003A&A...397..177B
ADC_Keywords: Infrared sources ; Clusters, galaxy ; Associations, stellar ; Morphology Keywords: Galaxy: open clusters and associations: general - Catalogs - Infrared: general Description: We compiled a catalogue of infrared star clusters in the Galaxy, which are most of them embedded. It condenses the growing literature information. We also include in the sample infrared stellar groups which are less dense than star clusters, such as those embedded in the dark clouds Taurus-Auriga and Chamaleon I. We provide galactic and equatorial coordinates, angular dimensions, different designations and related objects such as nebulae. A total of 189 infrared clusters and 87 embedded stellar groups are included. A fraction of 25% of the embedded clusters are projected close to each other in pair or triplet systems, indicating that multiplicity plays an important role in star cluster formation. File Summary:
