cds-question@unistra.frglobular-star-clustersopen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryh-alpha-photometryUsing Hubble Space Telescope (HST) WFPC2 images, we have obtained U, B, V, I, and H{alpha} photometry for 76 star clusters in the nuclear star-forming ring of the barred spiral galaxy NGC 4314. These clusters are likely associated with an inner inner Lindblad resonance (IILR). The blue colors and H{alpha} emission for most of these clusters imply very young ages of 115 Myr. Age estimates based on several reddening-free parameters indicate that the present epoch of star formation has lasted at least 30Myr. By estimating the masses of stars in the clusters and comparing with the H{alpha} luminosity, we conclude that a significant fraction of ongoing star formation in the nuclear ring of NGC 4314 occurs in clusters. The cluster masses identify these as young open clusters, not young globular clusters.2002AJ....123.1411Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/123/1411CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/123/1411https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/123/1411http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/123/1411https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/123/1411https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/123/1411http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/123/1411GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/123/1411/table2 (Nuclear Ring Cluster Photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/123/1411/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/123/1411/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/123/1411/table2?GETtext/xml+votable180.050000true185.63500929.8929940.0055555555555555566/28495https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/123/1411?format=asciiOpticalInfrareddefaultJ/AJ/123/1411/table2Nuclear Ring Cluster PhotometryrecnoRecord number assigned by the VizieR team.
