cds-question@unistra.frh-ii-regionspre-main-sequence-starsinfrared-photometryNear-IR imaging in the direction of the IRAS 15408-5356 point source, which is associated with the RCW 95 HII region, revealed a young and massive stellar cluster. We detected 136 member candidates up to our completeness limit, embedded in an infrared nebula and concentrated in an area of about 3pc^2^. About 60% of the candidates detected in all three of the J, H, and K bands present infrared excess at 2.2{mu}m. he UV photons provided by the most massive stars are enough to explain the observed free-free emission at radio wavelengths and the integrated infrared luminosity produced by the heated dust. The near-IR counterpart of the IRAS point source was identified using a more accurate position from the Midcourse Space Experiment (MSX) catalog; it coincides with the peak of emission in the MSX mid-IR bands. The measured integrated flux density of the infrared nebula at the K band is compatible with the expected free-free emission derived from the radio data, but an excess at the J and H bands was detected and may be due to either nonhomogeneous absorption across the nebula or to the presence of scattered stellar light, more prominent at smaller wavelengths.2004AJ....128.2364Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/128/2364CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/128/2364https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/128/2364http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/128/2364https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/128/2364https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/128/2364http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/128/2364GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/128/2364/table1 (List of the Selected Near-Infrared Sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/2364/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/2364/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/2364/table1?GETtext/xml+votable180.050000true236.1808333-54.098250.0055555555555555566/418208.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/128/2364?format=asciiInfrareddefaultJ/AJ/128/2364/table1List of the Selected Near-Infrared SourcesrecnoRecord number assigned by the VizieR team.
