cds-question@unistra.frmagellanic-cloudsopen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryWe present a new photometry of the Small Magellanic Cloud star cluster NGC 458 in UBVI filters. We determine the reddening E(B-V)=0.04+/-0.02. By comparison with the isochrones by Bertelli et al. (1994, Cat. <J/A+AS/106/275>) we derive an age of ~140Myr. Three candidate blue straggler stars are proposed. The evolved "blue loop'' stars of NGC 458 have masses between 4 and 5M_{sun}_ and are hotter than model predictions.2003A&A...400..917Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/400/917CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/400/917https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/400/917http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/400/917https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/400/917https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/400/917http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/400/917GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/400/917/table1 (Photometry of NGC 458)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/400/917/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/400/917/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/400/917/table1?GETtext/xml+votable180.050000true19.03065417-71.681706940.005555555555555556Cone search capability for table J/A+A/400/917/table2 (Blue loop stars in NGC 458)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/400/917/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/400/917/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/400/917/table2?GETtext/xml+votable180.050000true18.7205231-71.55225110.0055555555555555566/33307 33329https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/400/917?format=asciiOpticalInfrareddefaultJ/A+A/400/917/table1Photometry of NGC 458recnoRecord number assigned by the VizieR team.
