cds-question@unistra.fropen-star-clusterssupergiant-starsinfrared-photometryWe report on the unprecedented red supergiant (RSG) population of a massive young cluster, located at the base of the Scutum-Crux Galactic arm. We identify candidate cluster RSGs based on 2MASS photometry and medium-resolution spectroscopy. With follow-up high-resolution spectroscopy, we use CO band-head equivalent width and high-precision radial velocity measurements to identify a core grouping of 26 physically associated RSGs-the largest such cluster known to date.2007ApJ...671..781Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/671/781CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/671/781https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/671/781http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/671/781https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/671/781https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/671/781http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/671/781GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/671/781/table1 (Observational data for the brightest stars in the 2MASS-PSC within 7' of the cluster center)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/671/781/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/671/781/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/671/781/table1?GETtext/xml+votable180.050000true279.76-6.0862780.0055555555555555566/30219 30222 30241 302448.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/671/781?format=asciiInfrareddefaultJ/ApJ/671/781/table1Observational data for the brightest stars in the 2MASS-PSC within 7' of the cluster centerSeqSequential number (1)meta.id;meta.mainintprimaryDEJ2000Declination (J2000.0)pos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
