cds-question@unistra.frmolecular-cloudsmagellanic-cloudsh-ii-regionsradio-sourcesWe studied star formation activities in the molecular clouds in the Large Magellanic Cloud. We have utilized the second catalog of 272 molecular clouds obtained by NANTEN (4m radio telescope of Nagoya University at Las Campanas Observatory, Chile) to compare the cloud distribution with signatures of massive star formation including stellar clusters, and optical and radio HII regions. We find that the molecular clouds are classified into three types according to the activities of massive star formation: Type I shows no signature of massive star formation; Type II is associated with relatively small HII region(s); and Type III with both HII region(s) and young stellar cluster(s). The radio continuum sources were used to confirm that Type I giant molecular clouds (GMCs) do not host optically hidden HII regions. These signatures of massive star formation show a good spatial correlation with the molecular clouds in the sense that they are located within ~100pc of the molecular clouds.2009ApJS..184....1Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/184/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/232 : Nebulae in the Magellanic Clouds (Davies+ 1976)J/PASJ/53/971 : CO catalog of LMC molecular clouds (Mizuno+, 2001)J/ApJS/178/56 : CO observations of LMC Giant Molecular clouds (Fukui+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/184/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/184/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/184/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/184/1https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/184/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/184/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/184/1/table2 (Associated HII regions, OB associations, and young clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/184/1/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/184/1/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/184/1/table2?GETtext/xml+votable180.050000true71.8766667-69.16916670.0055555555555555565/8263 8269 8272 8274 8275 8276 8278 8280 6/33047 33051 33092 33094 33095 33110 33116 33124 33126 33127 33128 33129https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/184/1?format=asciiRadiodefaultJ/ApJS/184/1/table2Associated HII regions, OB associations, and young clustersrecnoRecord number assigned by the VizieR team.
