cds-question@unistra.frh-ii-regionsmolecular-cloudsinfrared-photometryWe present the results of an imaging survey, from the optical to the mid-infrared, of the dark cloud associated with Car I, a dense cloud that is subject to an intense ultraviolet radiation field from the rich stellar cluster Trumpler 14. New ground-based broad- and narrow-band near-infrared and narrow-band optical images are analysed in combination with archived Spitzer/Infra-Red Array Camera (IRAC) images to study this photodissociation region (PDR) and the triggering of a new generation of stars within the cloud, particularly close to its edges. Evidence is given of a clumpy morphology of the dense cloud. The ionization/dissociation front is delineated at the edges of these clumps. The existence of a number of embedded low- to intermediate-mass pre-main-sequence objects is confirmed by their considerable infrared excesses arising from discs and/or detectable X-ray emission. Most of the young stellar objects (YSOs) are located on or just behind ionization fronts, though a few are also outside the cloud. The infrared properties of the YSOs are discussed.2006MNRAS.367..513Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/367/513CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/355/1237 : JHKs photometry of G287.84-0.82 members (Hagele+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/367/513https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/367/513http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/367/513https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/367/513https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/367/513http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/367/513GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/367/513/table2 (Coordinates and photometry of sources with infrared excess.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/367/513/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/367/513/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/367/513/table2?GETtext/xml+votable180.050000true160.8295833-59.590750.0055555555555555566/38016https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/367/513?format=asciiInfrareddefaultJ/MNRAS/367/513/table2Coordinates and photometry of sources with infrared excess.RemRemarks (2)meta.notecharrecnoRecord number assigned by the VizieR team.
