cds-question@unistra.fropen-star-clustersinfrared-photometrydwarf-starsWe present 24um photometry of the intermediate-age open cluster Praesepe. We assemble a catalog of 193 probable cluster members that are detected in optical databases, the Two Micron All Sky Survey (2MASS), and at 24um, within an area of ~2.47deg^2^. Mid-IR excesses indicating debris disks are found for one early-type and for three solar-type stars. Corrections for sampling statistics yield a 24um excess fraction (debris disk fraction) of 6.5%+/-4.1% for luminous and 1.9%+/-1.2% for solar-type stars. The incidence of excesses is in agreement with the decay trend of debris disks as a function of age observed for other cluster and field stars.2009ApJ...697.1578Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/697/1578CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/257 : Proper Motions in Praesepe (Wang+, 1995)J/A+A/510/A27 : Very low mass stars in Praesepe (Boudreault+, 2010)J/AJ/134/2340 : Membership of Praesepe and Coma Berenices clusters (Kraus+,J/AJ/124/1570 : JHKs photometry in Praesepe (Adams+, 2002)J/A+A/375/989 : JHK photometry of Praesepe low-mass stars (Bouvier+, 2001)J/A+AS/109/29 : Very low mass stars in Praesepe (Hambly+, 1995)http://www.univie.ac.at/webda/navigation.html : WEBDA database accesshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/697/1578https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/697/1578http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/697/1578https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/697/1578https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/697/1578http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/697/1578GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/697/1578/table1 (Photometry of Praesepe members in the 24{mu}m band)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/697/1578/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/697/1578/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/697/1578/table1?GETtext/xml+votable180.050000true129.124291718.96570.0055555555555555566/4687 4696 4698 4699 4709 4720 47216.772611666688002e-21 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/697/1578?format=asciiInfrareddefaultJ/ApJ/697/1578/table1Photometry of Praesepe members in the 24{mu}m bandrecnoRecord number assigned by the VizieR team.
