Characterizing star cluster formation with WISE: 652 newly found star
  clusters and candidates
  We report the discovery of 652 star clusters, stellar groups and candidates
in the Milky Way with WISE. Most of the objects are projected close to Galactic
Plane and are embedded clusters. The present sample complements a similar study
(Paper I) 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 9
cluster candidates in the list, and derive their parameters, confirming them as
embedded clusters.
