cds-question@unistra.frseyfert-galaxiesspectroscopyradial-velocityGas inflowing along stellar bars is often stalled at the location of circumnuclear rings, which form an effective reservoir for massive star formation and thus shape the central regions of galaxies. However, how exactly star formation proceeds within these circumnuclear starburst rings is the subject of debate. Two main scenarios for this process have been put forward. In the first, the onset of star formation is regulated by the total amount of gas present in the ring with star forming starting, once a mass threshold has been reached, in "random" positions within the ring like "popcorn". In the second, star formation primarily takes place near the locations where the gas enters the ring. This scenario has been dubbed "pearls-on-a-string". Here we combine new optical IFU data covering the full stellar bar with existing multiwavelength data to study the 580pc radius circumnuclear starburst ring in detail in the nearby spiral galaxy NGC 6951. Using Hubble Space Telescope (HST) archival data together with SAURON and OASIS IFU data, we derive the ages and stellar masses of star clusters, as well as the total stellar content of the central region.2013A&A...551A..81Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/551/A81CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/551/A81https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/551/A81http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/551/A81https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/551/A81https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/551/A81http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/551/A81GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/551/A81/list (List of maps)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A81/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A81/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A81/list?GETtext/xml+votable180.050000true309.3088458366.105580560.005555555555555556Cone search capability for table J/A+A/551/A81/table4 (Candidate star clusters detected with IRAF/DAOPHOT and SExtractor)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A81/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A81/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A81/table4?GETtext/xml+votable180.050000true309.308503166.10680280.0055555555555555566/15955https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/551/A81?format=asciiOpticaldefaultJ/A+A/551/A81/listList of mapsNz?
