cds-question@unistra.fropen-star-clustersyoung-stellar-objectspre-main-sequence-starsinfrared-photometryTo study how the structure of the envelopes of young stellar objects (YSOs) evolve, we carried out a deep JHK'-band imaging survey of the M17 star-forming region using a near-infrared camera and the Infrared Camera and Spectrograph with adaptive optics mounted on the Subaru Telescope. In this survey, we found 51 dark silhouettes against bright near-infrared nebula emissions as background lights. They are regarded as envelopes associated with YSOs due to their size and association with the YSOs. We derived size, morphology, extinction, and mass for each silhouette envelope.2008ApJ...672..398Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/672/398CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/672/398https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/672/398http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/672/398https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/672/398https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/672/398http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/672/398GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/672/398/table3 (Photometry and derived parameters of silhouette and YSOs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/672/398/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/672/398/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/672/398/table3?GETtext/xml+votable180.050000true275.098925-16.170169440.0055555555555555566/29116 291181.143914381504295e-19 5.675559890447326e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/672/398?format=asciiInfrareddefaultJ/ApJ/672/398/table3Photometry and derived parameters of silhouette and YSOsrecnoRecord number assigned by the VizieR team.
