J/A+A/447/921       Galactic Open Cluster Candidates         (Kronberger+, 2006)

New Galactic Open Cluster Candidates from DSS and 2MASS Imagery. Kronberger M., Teutsch P., Alessi B., Steine M., Ferrero L., Graczewski K., Juchert M., Patchick D., Riddle D., Saloranta J., Schoenball M., Watson C. <Astron. Astrophys. 447, 921 (2006)> =2006A&A...447..921K
ADC_Keywords: Clusters, open ; Planetary nebulae ; Morphology Keywords: Galaxy: open clusters and associations: general - HII regions - reflection nebulae - planetary nebulae: general Abstract: An inspection of DSS and 2MASS images of selected Milky Way regions led to the discovery of 66 stellar groupings whose morphologies, color-magnitude diagrams and stellar density distributions suggest that these objects are possible open clusters that are not yet listed in any catalogue. For 24 of these, which we consider to be the most likely candidates, we provide extensive descriptions on the basis of 2MASS photometry and their visual impression on DSS and 2MASS. Of those cluster candidates, 9 have fundamental parameters determined by fitting the color-magnitude diagrams with solar metallicity Padova isochrones. Additional 10 cluster candidates have distance moduli and reddenings derived from K magnitudes and (J-K) color indices of helium-burning red clump stars. As an addendum, we provide a list of a number of apparently yet unknown galactic and extragalactic objects which were also discovered during the survey. File Summary:
