cds-question@unistra.fryoung-stellar-objectspre-main-sequence-starsinfrared-sourceseffective-temperatureWe present high-resolution (R~18000), high signal-to-noise ratio, 2{mu}m spectra of 52 IR-selected Class I and flat-spectrum young stellar objects in the Taurus-Auriga, {rho} Ophiuchi, Serpens, Perseus, and Corona Australis dark clouds. We detect key absorption lines in 41 objects and fit synthetic spectra generated from pre-main-sequence models to deduce the effective temperatures, surface gravities, near-IR veilings, rotation velocities, and radial velocities of each of these 41 sources.2005AJ....130.1145Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/1145CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/1145https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/1145http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/1145https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/1145https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/1145http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/1145GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/130/1145/table1 (Journal of observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/1145/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/1145/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/1145/table1?GETtext/xml+votable180.050000true61.179583326.31608330.0055555555555555566/862 1031 1037 1054 1061 1074 1082 1136 1154 1159 1168 2622 2737 7264 8440 9146 12454 13301 14278 14709 14772 15249 18482 23357 25708 27132 27459 27462 28605 30366 30490 30505 30665 30833 31087 31817 32757 42970 42981 42992 44284 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/130/1145?format=asciiInfrareddefaultJ/AJ/130/1145/table1Journal of observationsrecnoRecord number assigned by the VizieR team.
