cds-question@unistra.frmolecular-cloudsyoung-stellar-objectsinfrared-sourcesspectroscopic-binary-starsWe have conducted near-infrared spectroscopy of 26 faint objects around young stellar objects in the Taurus molecular cloud. These objects were detected during a course of near-infrared coronagraphic searches for companions around 72 young stellar objects with the Subaru Telescope and the near-infrared coronagraph CIAO (coronagraphic imager with adaptive optics). A comparison of the Subaru and HST archive images revealed that three central stars and faint companions share common proper motions, suggesting that they are physically associated with each other. None of the 26 sources show deep water absorption bands at near-infrared, except for DH Tau B. This result indicates that all of them, but DH Tau B, have a high photospheric temperature or a large amount of excess from circumstellar materials.2008PASJ...60..209Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASJ/60/209CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASJ/60/209https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASJ/60/209http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASJ/60/209https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASJ/60/209https://vizier.iucaa.in/viz-bin/votable?-source=J/PASJ/60/209http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASJ/60/209GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASJ/60/209/table1 (Companion candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASJ/60/209/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/PASJ/60/209/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASJ/60/209/table1?GETtext/xml+votable180.050000true68.730916724.48144440.0055555555555555565/292 6/81 257 1031 1042 1050-1051 1063 1066 1069 1075 1081 1114 1174 22888 23396 23447 23478 23497 23549 23738 23774 24066https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASJ/60/209?format=asciiInfrareddefaultJ/PASJ/60/209/table1Companion candidatesrecnoRecord number assigned by the VizieR team.
