cds-question@unistra.frvisible-astronomybroad-band-photometryopen-star-clustersTwo new Galactic Wolf-Rayet stars were found in open clusters: a WN4 star in the O9 cluster Sher 1 and a WN7 star in the O7 cluster Westerlund 2. This confirms a previous trend, namely that fainter, hotter WN stars tend to be older than brighter, cooler WN stars. This may be a consequence of evolution via extreme mass loss.1991AJ....102..642Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/102/642CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/102/642https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/102/642http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/102/642https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/102/642https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/102/642http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/102/642GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/102/642/west2 (Positions, identifications, UBV, membership and spectral types in Westerlund 2 (from tables 2+3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/102/642/west2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/102/642/west2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/102/642/west2?GETtext/xml+votable180.050000true156.0102083-57.74327780.0055555555555555566/373433.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/102/642?format=asciiOpticaldefaultJ/AJ/102/642/west2Positions, identifications, UBV, membership and spectral types in Westerlund 2 (from tables 2+3)RAJ2000Right Ascension J2000 (1)pos.eq.ra;meta.mainDEJ2000Declination J2000 (1)pos.eq.dec;meta.mainXposCCD position (from WEBDA)pixpos.cartesian.x;instr.detfloatYposCCD position (from WEBDA)pixpos.cartesian.y;instr.detfloatVmagJohnson V-band magnitudemagphot.mag;em.opt.VfloatB-VJohnson B-V color indexmagphot.color;em.opt.B;em.opt.VfloatU-BJohnson U-B color indexmagphot.color;em.opt.U;em.opt.BfloatMm[m nm] Membership status (member or non-member)meta.code.membercharSpMK spectral type for 9 stars (from table3)src.spTypecharSimbadSimbad column added by the CDSmeta.ref.urlcharMSP[18/444] Identification of the star in paper, <Cl* Westerlund 2 MSP NNN> in Simbadmeta.id;meta.mainintprimaryMV[1/9]?
