We evaluate the distribution of N* in the Small Magellanic Cloud using recent broadband optical and space-ultraviolet data, with special attention to the lowest values of N*. We find that the power-law distribution in N* continues smoothly down to N*=1. This strongly suggests that the formation of field massive stars is a continuous process with those in associations and that the field stars do not originate from a different star formation mode.2004AJ....127.1632Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/1632CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/236 : UBVR CCD survey of the Magellanic clouds (Massey+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/1632https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/1632http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/1632https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/1632https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/1632http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/1632GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/1632/table2 (Groups from the candidate OB sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1632/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1632/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1632/table2?GETtext/xml+votable180.050000true11.3029-73.3820.005555555555555556Cone search capability for table J/AJ/127/1632/table3 (Groups from the candidate O-star sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1632/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1632/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1632/table3?GETtext/xml+votable180.050000true11.9117-73.13850.005555555555555556Cone search capability for table J/AJ/127/1632/table4 (Group Membership for the Candidate OB Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1632/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1632/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1632/table4?GETtext/xml+votable180.050000true10.1171-73.54250.005555555555555556Cone search capability for table J/AJ/127/1632/table5 (Group Membership for the Candidate O Star Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1632/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1632/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1632/table5?GETtext/xml+votable180.050000true11.144-73.15970.0055555555555555565/8323 8326 6/33297-33299 33316-33317 33319 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/1632?format=asciiOpticalInfrareddefaultJ/AJ/127/1632/table2Groups from the candidate OB samplerecnoRecord number assigned by the VizieR team.
