cds-question@unistra.fropen-star-clustersx-ray-sourcesphotometryWe present X-ray spectral and timing analysis of members of the young open cluster IC 2391 observed with the XMM-Newton observatory. We detected 99 X-ray sources by analysing the summed data obtained from MOS1, MOS2 and pn detectors of the EPIC camera; 24 of them are members, or probable members, of the cluster. Stars of all spectral types have been detected, from the early-types to the late-M dwarfs.2005A&A...430..287Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/430/287CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/xmm : XMM-Newton Observation Log (XMM-Newton SOC, 2002)IX/37 : XMM-Newton Serendipitous Source Catalogue (1XMM) (XMM-SSC, 2003)J/MNRAS/355/959 : Proper motions of IC 2391 possible members (Dodd+, 2004)J/ApJS/134/103 : Low-mass members of IC 2391 (Barrado y Navascues+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/430/287https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/430/287http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/430/287https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/430/287https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/430/287http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/430/287GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/430/287/table1 (XMM-Newton sources in the IC 2391 region, as detected in the combined EPIC image.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/430/287/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/430/287/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/430/287/table1?GETtext/xml+votable180.050000true130.02785833-53.025988890.005555555555555556Cone search capability for table J/A+A/430/287/table2 (X-ray and optical properties of IC 2391 members, and upper limits in the combined EPIC image.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/430/287/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/430/287/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/430/287/table2?GETtext/xml+votable180.050000true130.07292083-53.015469440.0055555555555555566/37790https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/430/287?format=asciiX-rayOpticaldefaultJ/A+A/430/287/table1XMM-Newton sources in the IC 2391 region, as detected in the combined EPIC image.[MMP2005]Sequential numbermeta.id;meta.mainintprimaryrecnoRecord number assigned by the VizieR team.
