cds-question@unistra.frgalaxiesstellar-associationshst-photometryRecent studies have started to cast doubt on the assumption that most stars are formed in clusters. Observational studies of field stars and star cluster systems in nearby galaxies can lead to better constraints on the fraction of stars forming in clusters. Ultimately this may lead to a better understanding of star formation in galaxies, and galaxy evolution in general. We aim to constrain the amount of star formation happening in long-lived clusters for four galaxies through the homogeneous, simultaneous study of field stars and star clusters.2011A&A...529A..25Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/529/A25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/529/A25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/529/A25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/529/A25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/529/A25https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/529/A25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/529/A25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/529/A25/clusters (Clusters found in the studied galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/529/A25/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/529/A25/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/529/A25/clusters?GETtext/xml+votable180.050000true3.548875-23.19046940.005555555555555556Cone search capability for table J/A+A/529/A25/table24 (Journal of the observations and 50% completeness limits for field stars (tables 2 and 4 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/529/A25/table24?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/529/A25/table24?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/529/A25/table24?GETtext/xml+votable180.050000true204.25-29.827220.0055555555555555566/16441 16605 28535 33193 438812.0401237512456292e-19 6.367785378457404e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/529/A25?format=asciidefaultJ/A+A/529/A25/clustersClusters found in the studied galaxiesrecnoRecord number assigned by the VizieR team.
