cds-question@unistra.frgalaxiesphotometryopen-star-clustersultraviolet-photometryWe investigate the star cluster system in the starburst galaxy NGC 7673 using archival Hubble Space Telescope WFPC2 broad-band images. For the first time we are able to examine the internal structures of the prominent optical clumps in this galaxy. The clumps are composed of young stars, 16-33% of which are in bright star clusters. We identify 268 star cluster candidates in both the F555W and F814W images, and 50 clusters with the F255W filter. These data allow us to estimate ages and masses using color-magnitude and two-color diagrams for our sample. We find a population of young, <6Myr clusters located throughout the galaxy with concentrations in the clumps. Star cluster mass estimates are 5-50x10^4^M_{sun}_ for the brightest objects. The starburst remains active in physically well-separated regions, indicating a widespread starburst trigger. We discuss clump lifetimes, their implications for the future evolution of NGC 7673, and possible relationships to high redshift starbursts.2002A&A...391..857Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/391/857CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/391/857https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/391/857http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/391/857https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/391/857https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/391/857http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/391/857GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/391/857/table2 (Parameters for clusters detected in the F255W (UV), F555W (V) and F814W (I) filters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/391/857/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/391/857/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/391/857/table2?GETtext/xml+votable180.050000true351.92162523.58858890.0055555555555555566/20177https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/391/857?format=asciiUVOpticaldefaultJ/A+A/391/857/table2Parameters for clusters detected in the F255W (UV), F555W (V) and F814W (I) filtersrecnoRecord number assigned by the VizieR team.
