cds-question@unistra.fropen-star-clustersx-ray-sourcesinfrared-photometryWe describe Chandra/ACIS-I observations of the massive ~13-14Myr-old cluster, h Persei, part of the famous Double Cluster (h and {chi} Per) in Perseus. Combining the list of Chandra-detected sources with new optical/IR photometry and optical spectroscopy reveals ~165 X-ray bright stars with V<~23. Roughly 142 have optical magnitudes and colors consistent with cluster membership.2009AJ....137.3210Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/137/3210CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)J/A+A/394/479 : uvby{beta} photometry of h and chi Per (Capilla+, 2002)J/PASP/114/233 : h and {chi} Per memberships (Uribe+, 2002)J/ApJ/576/880 : CCD UBV photometry of h and {chi} Per (Slesnick+, 2002)J/ApJ/669/L33 : H{alpha} emission sources in h and {chi} Per (Currie+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/137/3210https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/137/3210http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/137/3210https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/137/3210https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/137/3210http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/137/3210GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/137/3210/table1 (Chandra/ACIS Detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/137/3210/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/137/3210/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/137/3210/table1?GETtext/xml+votable180.050000true34.929557.10050.005555555555555556Cone search capability for table J/AJ/137/3210/table2 (Catalog of Chandra sources with optical counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/137/3210/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/137/3210/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/137/3210/table2?GETtext/xml+votable180.050000true34.915157.05970.0055555555555555566/3256 32582.0616683193919197e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/137/3210?format=asciiX-rayInfrareddefaultJ/AJ/137/3210/table1Chandra/ACIS DetectionsrecnoRecord number assigned by the VizieR team.
