cds-question@unistra.frh-ii-regionsx-ray-sourcesinfrared-sourcesinfrared-photometryThe IC 1396N cometary globule (CG) within the large nearby HII region IC 1396 has been observed with the ACIS detector on board the Chandra X-Ray Observatory. We detect 117 X-ray sources, of which ~50-60 are likely members of the young open cluster Trumpler 37 dispersed throughout the HII region, and 25 are associated with young stars formed within the globule. Infrared photometry (2MASS and Spitzer) shows that the X-ray population is very young: 3 older Class III stars, 16 classical T Tauri stars, and 6 protostars including a Class 0/I system.2007ApJ...654..316Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/654/316CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/654/316https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/654/316http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/654/316https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/654/316https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/654/316http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/654/316GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/654/316/table1 (X-Ray Sources in the IC 1396N Field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/654/316/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/654/316/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/654/316/table1?GETtext/xml+votable180.050000true324.861261158.21118890.005555555555555556Cone search capability for table J/ApJ/654/316/table3 (NIR Globule Sample of Nisini et al.
