cds-question@unistra.frmagellanic-cloudsmorgan-keenan-classificationh-ii-regionsWe present a spectroscopic study of the N159/N160 massive star-forming region south of 30 Doradus in the Large Magellanic Cloud, classifying a total of 189 stars in the field of the complex. Most of them belong to O and early B spectral classes; we have also found some uncommon and very interesting spectra, including members of the Onfp class, a Be P Cygni star, and some possible multiple systems. Using spectral types as broad indicators of evolutionary stages, we considered the evolutionary status of the region as a whole. We infer that massive stars at different evolutionary stages are present throughout the region, favoring the idea of a common time for the origin of recent star formation in the N159/N160 complex as a whole, while sequential star formation at different rates is probably present in several subregions.2009AJ....138..510Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/138/510CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/422/129 : JHKs photometry in N159 (LMC) (Meynadier+, 2004)J/A+A/453/517 : JKs photometry of N159A (Testor+, 2006)J/A+A/469/459 : K magnitudes of N159-5 (LMC) (Testor+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/138/510https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/138/510http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/138/510https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/138/510https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/138/510http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/138/510GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/138/510/table1 (Spectral classification of 189 stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/138/510/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/138/510/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/138/510/table1?GETtext/xml+votable180.050000true84.4206667-69.80913890.0055555555555555566/33091 33094https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/138/510?format=asciiOpticaldefaultJ/AJ/138/510/notesIndividual notesrecnoRecord number assigned by the VizieR team.
