cds-question@unistra.frpre-main-sequence-starsinfrared-photometryWe present the results of deep (K_s_=18.9) sub-arcsec resolution (0.3") imaging observations of the Cederblad 110 region in the Chamaeleon I dark cloud. This region (roughly 5'x5') is characterized by the presence of six ISOCAM-detected young stellar objects (YSOs). Our images have recovered all these sources at near-infrared (near-IR) wavelengths. Ced 110 IRS4, the brightest object in the region, is associated with a remarkable near-IR bipolar nebulosity. Ced 110 IRS6 is resolved in a double system IRS6a and IRS6b with a separation of ~2" (~320AU at the distance of the Cha I cloud). We have combined 1.3 mm, far and mid-IR fluxes from the literature with our JHK data and obtained the spectral energy distributions (SEDs) for three (IRS4, IRS6a and ISO-ChaI86) of the six ISOCAM sources in the region. We modelled the SEDs of IRS6a and ISO-ChaI86 with a spherically symmetric dusty envelope, using the DUSTY code. These objects are clear Class I sources of the cloud. Finally, we report the detection of three new objects in this region (NIR 72, 84 and 89) with significant near-IR excess. If these sources are associated with the cloud, the derived luminosities and masses suggest that they are candidate young brown dwarfs of Chamaeleon I.2001A&A...376..907Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/376/907CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/376/907https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/376/907http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/376/907https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/376/907https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/376/907http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/376/907GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/376/907/catalog (List of the near-infrared sources (NIR) observed in the Ced110 region)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/376/907/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/376/907/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/376/907/catalog?GETtext/xml+votable180.050000true166.5200417-77.36261110.0055555555555555566/36956https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/376/907?format=asciiInfrareddefaultJ/A+A/376/907/catalogList of the near-infrared sources (NIR) observed in the Ced110 regionrecnoRecord number assigned by the VizieR team.
