cds-question@unistra.frmolecular-cloudspre-main-sequence-starsline-intensitiesWe discuss the results of the optical spectroscopic follow-up of pre-main-sequence (PMS) objects and candidates selected in the Chamaeleon II dark cloud based on data from the Spitzer Legacy survey "From Molecular Cores to Planet Forming Disks" (c2d) and from previous surveys. Our sample includes both objects with infrared excess selected according to c2d criteria and referred to as young stellar objects and other cloud members and candidates selected from complementary optical and near-infrared data. We characterize the sample of objects by deriving their physical parameters.2008ApJ...680.1295Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/680/1295CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/399/995 : SOFI and ISOCAM observations of Cha II (Persi+, 2003)J/A+A/470/281 : WFI optical photometry in Cha II dark cloud (Spezzi+, 2007)J/ApJ/676/427 : MIPS and IRAC Chamaeleon II PMS data (Alcala+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/680/1295https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/680/1295http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/680/1295https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/680/1295https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/680/1295http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/680/1295GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/680/1295/tables (Spectral types, line widths and physical parameters for pre-main-sequence objects and candidates in Cha II)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/680/1295/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/680/1295/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/680/1295/tables?GETtext/xml+votable180.050000true191.2767917-77.33708890.0055555555555555565/10283 6/41126 41127https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/680/1295?format=asciiOpticaldefaultJ/ApJ/680/1295/tablesSpectral types, line widths and physical parameters for pre-main-sequence objects and candidates in Cha IIrecnoRecord number assigned by the VizieR team.
