We observed, using Spitzer's IRAC and MIPS instruments, in six wavelength bands from 3 to 70um, to detect thermal emission from circumstellar disks and protostellar envelopes and to classify stars using color-color diagrams and SEDs. These data are combined with Chandra observations to examine the effects of circumstellar disks on stellar X-ray properties. Young diskless stars were also identified from their increased X-ray emission. We have identified 138 YSOs in Serpens: 22 Class 0/I, 16 flat-spectrum, 62 Class II, 17 transition disk, and 21 Class III stars; 60 of these exhibit X-ray emission.2007ApJ...669..493Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/669/493CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/421/623 : ISOCAM survey of YSOs in Serpens Cloud Core (Kaas+, 2004)J/A+A/463/275 : Chandra obs. of Serpens star-forming region (Giardino+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/669/493https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/669/493http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/669/493https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/669/493https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/669/493http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/669/493GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/669/493/catalog (Catalog of young stellar objects in Serpens core)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/669/493/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/669/493/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/669/493/catalog?GETtext/xml+votable180.050000true277.50870831.23300280.0055555555555555566/303668.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/669/493?format=asciiX-rayInfraredRadiodefaultJ/ApJ/669/493/catalogCatalog of young stellar objects in Serpens coref_3.6mag[d] Flag on 3.6mag (1)meta.codechar5.8mag?
