cds-question@unistra.fropen-star-clusterspeculiar-variable-starsccd-photometryinfrared-photometryvisible-astronomyphotometryWe have identified a large sample of probable low-mass members of the young open cluster IC 2391 based on optical (VRIZ) and infrared (JHKs) photometry. Our sample includes 50 probable members and 82 possible members, both very low-mass stars and brown dwarfs. We also provide accurate positions for these stars and brown dwarf candidates derived from red UK Schmidt plates measured using the microdensitometer SuperCOSMOS. Assuming an age of 53Myr, we estimate that we have reached a mass of 0.025M_{sun}_, if the identified objects are indeed members of IC 2391.2001ApJS..134..103Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/134/103CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/134/103https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/134/103http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/134/103https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/134/103https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/134/103http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/134/103GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/134/103/table2 (IC 2391 candidate members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/134/103/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/134/103/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/134/103/table2?GETtext/xml+votable180.050000true128.9107917-53.22097220.0055555555555555565/9447 6/37787 37809 37812https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/134/103?format=asciiOpticalInfrareddefaultJ/ApJS/134/103/table2IC 2391 candidate membersrecnoRecord number assigned by the VizieR team.
