cds-question@unistra.frinfrared-sourcespre-main-sequence-starsinfrared-photometryWe present high-resolution near-infrared and mid-infrared imaging, mid-infrared spectroscopy and millimetre-wavelength continuum observations of the nearby massive star-forming complex IRAS 09002-4732. A rich cluster of young stars displaying near-infrared excess emission is detected. We identify the ionising source of the ultracompact H II region G268.42-0.85 and show that this star is the dominant heating and illuminating source of the region. Spectral type estimates based on different methods are consistent with a star of spectral type O9. The combination of the new observations with literature data allows us to set up the first structural model for the region.2005A&A...434..987Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/434/987CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/434/987https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/434/987http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/434/987https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/434/987https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/434/987http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/434/987GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/434/987/table5 (Near-infrared photometry and coordinates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/434/987/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/434/987/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/434/987/table5?GETtext/xml+votable180.050000true135.474167-47.7631390.0055555555555555566/37850 37872https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/434/987?format=asciiInfrareddefaultJ/A+A/434/987/table5Near-infrared photometry and coordinatesrecnoRecord number assigned by the VizieR team.
