cds-question@unistra.fropen-star-clustersinfrared-photometrydwarf-starspre-main-sequence-starsWe present new Spitzer Space Telescope observations of stars in the young (~5Myr) {gamma} Velorum stellar cluster. Combining optical and 2MASS photometry, we have selected 579 stars as candidate members of the cluster. With the addition of the Spitzer mid-infrared data, we have identified five debris disks around A-type stars and five to six debris disks around solar-type stars, indicating that the strong radiation field in the cluster does not completely suppress the production of planetesimals in the disks of cluster members. However, we find some evidence that the frequency of circumstellar primordial disks is lower, and the infrared flux excesses are smaller than for disks around stellar populations with similar ages.2008ApJ...686.1195Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/686/1195CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/280 : All-sky Compiled Catalogue of 2.5 million stars (Kharchenko+ 2009)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/131/1574 : Infrared photometry of IC348 members (Lada+, 2006)J/ApJ/638/897 : IR photometry in Trumpler 37 and NGC 7160 (Sicilia-Aguilar+,J/ApJ/651/L49 : Upper Sco OB association IRAC observations (Carpenter+, 2006)J/ApJ/662/1067 : Sptizer observations of sigma Orionis (Hernandez+, 2007)J/ApJ/671/1784 : Ori OB1 IRAC/MIPS observations (Hernandez+, 2007)J/ApJ/660/1532 : Spitzer/IRAC-MIPS survey of NGC 2244 (Balog+, 2007)J/ApJ/659/599 : IRAC and JHKs photometry of h and chi Persei (Currie+, 2007)J/ApJ/672/558 : MIPS observations of h and {chi} Persei (Currie+, 2008)J/ApJS/179/451 : Predicted IR excesses for protoplanetary disks (Kenyon+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/686/1195https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/686/1195http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/686/1195https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/686/1195https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/686/1195http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/686/1195GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/686/1195/table1 (Candidate members of the {gamma} Velorum cluster)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/686/1195/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/686/1195/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/686/1195/table1?GETtext/xml+votable180.050000true121.682875-47.53144440.0055555555555555566/39194 39205 39216 392186.772611666688002e-21 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/686/1195?format=asciiInfrareddefaultJ/ApJ/686/1195/table1Candidate members of the {gamma} Velorum clusterrecnoRecord number assigned by the VizieR team.
