cds-question@unistra.fropen-star-clustersinfrared-sourcesaccretioninfrared-photometryWe report the discovery of accretion disks associated with ~13Myr old intermediate/low-mass stars in h and {chi} Persei. Optical spectroscopy of ~5000 stars in these clusters and a surrounding halo population reveal 32 A-K stars with Halpha emission. Matching these stars with 2MASS and optical photometry yields 25 stars with the highest probability of cluster membership and EW(Halpha)>=5{AA}. Sixteen of these sources have EW(Halpha)>=10{AA}.2007ApJ...669L..33Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/669/L33CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/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/669/L33https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/669/L33http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/669/L33https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/669/L33https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/669/L33http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/669/L33GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/669/L33/table1 (H{alpha} emission sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/669/L33/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/669/L33/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/669/L33/table1?GETtext/xml+votable180.050000true35.590083357.06680560.0055555555555555566/3256 3257 32581.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/669/L33?format=asciiInfrareddefaultJ/ApJ/669/L33/table1H{alpha} emission sourcesrecnoRecord number assigned by the VizieR team.
