Search for Compact Stellar Groups in the Vicinity of IRAS Sources
  The results of a search for compact clusters in the vicinity of 19 IRAS
sources based on data from the GPS UKIDSS and Spitzer GLIMPSE surveys are
presented. Overall, clusters have been identified in 15 regions. Clusters are
identified for the first time in 4 regions (IRAS 18151-1208, IRAS 18316-0602,
18517+0437, 19110+1045). In 5 regions (IRAS 05168+3634, 05358+3543, IRAS
18507+0121, IRAS 20188+3928, IRAS 20198+3716) the compact groups we have
identified are substructures within more extended clusters. The radii of the
identified groups and the surface star density are widely scattered with ranges
of 0.3-2.7 pc and 4-1360 stars/pc^2, respectively. In 11 of the clusters, the
IRAS sources are associated with a pair or even a group of YSOs. The groups
identified in the near IR include representatives of a later evolutionary class
II among the stellar objects associated with the IRAS sources.
