cds-question@unistra.fropen-star-clustersastrometryinfrared-photometryYoung massive clusters are key to map the Milky Way's structure, and near-IR large area sky surveys have contributed strongly to the discovery of new obscured massive stellar clusters. We present the third article in a series of papers focused on young and massive clusters discovered in the VVV survey. This article is dedicated to the physical characterization of VVV CL086, using part of its OB-stellar population. We physically characterized the cluster using JHKs near-infrared photometry from ESO public survey VVV images, using the VVV-SkZ pipeline, and near-infrared K-band spectroscopy, following the methodology presented in the first article of the series. Individual distances for two observed stars indicate that the cluster is located at the far edge of the Galactic bar. These stars, which are probable cluster members from the statistically field-star decontaminated CMD, have spectral types between O9 and B0V. According to our analysis, this young cluster (1.0Myr<age<5.0Myr) is located at a distance of 11kpc, and we estimate a lower limit for the cluster total mass of 2800 solar masses. It is likely that the cluster contains even earlier and more massive stars.2014A&A...564L...9Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/564/L9CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/532/A131 : New Galactic star clusters in VVV survey (Borissova+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/564/L9https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/564/L9http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/564/L9https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/564/L9https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/564/L9http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/564/L9GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/564/L9/members (VVV CL086 star positions and magnitudes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/564/L9/members?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/564/L9/members?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/564/L9/members?GETtext/xml+votable180.050000true252.07216-45.43573390.0055555555555555566/422078.643406281242892e-20 1.6978332528839141e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/564/L9?format=asciiInfrareddefaultJ/A+A/564/L9/membersVVV CL086 star positions and magnitudesrecnoRecord number assigned by the VizieR team.
