cds-question@unistra.frmolecular-cloudspre-main-sequence-starsinfrared-photometryWe present the results of near-infrared imaging and low-resolution near-infrared spectroscopy of low-mass objects in the NGC 1333 molecular cloud. A JHK survey of an 11.4'x11.7' area of the northern cluster was conducted to a sensitivity of K<=16mag. Using near-infrared magnitudes and colors from this and previously published surveys, 25 brown dwarf candidates were selected toward the high-extinction cloud core. Spectra in the K band were obtained and comparisons of the depths of water vapor absorption bands in our candidate objects with a grid of dwarf, subgiant, and giant standards were made to derive spectral types. These data were then used to derive effective temperatures and stellar luminosities that, when combined with theoretical tracks and isochrones for pre-main-sequence objects, resulted in estimates for their masses and ages.2004AJ....127.1131Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/1131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/401/543 : XMM-Newton observations of NGC 1333 (Preibisch, 2003)J/A+AS/106/165 : Near-IR imaging photometry of NGC 1333 (Aspin+ 1994)J/AJ/111/1964 : JHK photometry of NGC 1333 (Lada+, 1996)J/ApJ/575/354 : Young stellar objects in the NGC 1333 (Getman+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/1131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/1131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/1131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/1131https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/1131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/1131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/1131/table1 (Photometry of northern NGC 1333 cluster)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1131/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1131/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1131/table1?GETtext/xml+votable180.050000true52.186833331.49161110.0055555555555555566/862https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/1131?format=asciiInfrareddefaultJ/AJ/127/1131/table1Photometry of northern NGC 1333 clusterrecnoRecord number assigned by the VizieR team.
