cds-question@unistra.fropen-star-clustersinterstellar-cloudsx-ray-sourcesproper-motionsThe mysterious high Galactic latitude cometary globule CG 12 has been observed with the ACIS detector on board the Chandra X-Ray Observatory. We detect 128 X-ray sources, of which half are likely young stars formed within the globule's head. This new population of >~50 T Tauri stars and one new embedded protostar is far larger than the previously reported few intermediate-mass and two protostellar members of the cloud.2008ApJ...673..331Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/673/331CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)J/MNRAS/355/1272 : BVIJHKs photometry around CG 12 (Maheswar+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/673/331https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/673/331http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/673/331https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/673/331https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/673/331http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/673/331GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/673/331/sources (Basic source properties, optical and NIR counterparts (tables 2 and 4 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/673/331/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/673/331/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/673/331/sources?GETtext/xml+votable180.050000true209.23758-39.89714390.0055555555555555566/43441 434448.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/673/331?format=asciiX-raydefaultJ/ApJ/673/331/sourcesBasic source properties, optical and NIR counterparts (tables 2 and 4 of paper)2MASS2MASS designation (HHMMSSss+DDMMSSs)meta.id.crosscharrecnoRecord number assigned by the VizieR team.
