cds-question@unistra.frinfrared-photometryspectroscopylate-type-starsopen-star-clustersI present new results from a continuing program to identify and characterize the low-mass stellar and substellar populations in the young cluster IC 348 (0.5 - 10 Myr). Optical spectroscopy has revealed young objects with spectral types as late as M8.25. The intrinsic J-H and H-K colors of these sources are dwarflike, whereas the R-I and I-J colors appear intermediate between the colors of dwarfs and giants. Furthermore, the spectra from 6500 to 9500 {AA} are reproduced well with averages of standard dwarf and giant spectra, suggesting that such averages should be used in the classification of young late-type sources.1999ApJ...525..466Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/525/466CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/525/466https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/525/466http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/525/466https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/525/466https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/525/466http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/525/466GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/525/466/table1 (Data for low-mass sources in IC 348)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/525/466/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/525/466/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/525/466/table1?GETtext/xml+votable180.050000true56.175208332.14955560.0055555555555555566/1539https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/525/466?format=asciiInfrareddefaultJ/ApJ/525/466/table1Data for low-mass sources in IC 348recnoRecord number assigned by the VizieR team.
