J/MNRAS/455/3126 New Galactic star clusters and candidates (Camargo+, 2016) ================================================================================ Characterizing star cluster formation with WISE: 652 newly found star clusters and candidates. Camargo D., Bica E., Bonatto C. =2016MNRAS.455.3126C (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Milky Way ; Clusters, open ; Associations, stellar ; Morphology Keywords: catalogues - Galaxy: disc - open clusters and associations: general - Galaxy: structure Abstract: We report the discovery of 652 star clusters, stellar groups and candidates in the Milky Way with Wide-field Infrared Survey Explorer (WISE). Most of the objects are projected close to Galactic plane and are embedded clusters. The present sample complements a similar study (Paper I, Bica et al., 2015, Cat. J/other/NewA/34.84) which provided 437 star clusters and alike. We find evidence that star formation processes span a wide range of sizes, from populous dense clusters to small compact embedded ones, sparse stellar groups or in relative isolation. The present list indicates multiple stellar generations during the embedded phase, with giant molecular clouds collapsing into several clumps composing an embedded cluster aggregate. We investigate the field star decontaminated colour-magnitude diagrams and radial density profiles of nine cluster candidates in the list, and derive their parameters, confirming them as embedded clusters. Description: We recently reported the discovery of 446 star clusters, stellar clusters and candidates, mostly projected on the Galactic disc. They were designated Camargo 1 (C1)-C446, in a series of analyses. (i) In Paper I (Bica et al., 2015, Cat. J/other/NewA/34.84, we presented the first large list: C1-C437. (ii) In Paper II (Camargo et al., 2015MNRAS.448.1930C), we analysed C438 and C439, two rare high Galactic latitude ECs that were formed in the halo. (iii) In Paper III (Camargo et al.. 2015MNRAS.450.4150C), we provided the ECs C440-C446, in a study of Spiral Arm tracers. This paper discoveries of star clusters and alike are designated C447-C1098, thus amounting to 652 new entries (Table 1).
