cds-question@unistra.frmolecular-cloudsyoung-stellar-objectsinfrared-photometryextinctionWe present observations of the Auriga-California Molecular Cloud (AMC) at 3.6, 4.5, 5.8, 8.0, 24, 70, and 160 {mu}m observed with the IRAC and MIPS detectors as part of the Spitzer Gould Belt Legacy Survey. The total mapped areas are 2.5 deg^2^ with IRAC and 10.47 deg^2^ with MIPS. This giant molecular cloud is one of two in the nearby Gould Belt of star-forming regions, the other being the Orion A Molecular Cloud (OMC). We compare source counts, colors, and magnitudes in our observed region to a subset of the SWIRE data that was processed through our pipeline. Using color-magnitude and color-color diagrams, we find evidence for a substantial population of 166 young stellar objects (YSOs) in the cloud, many of which were previously unknown. Most of this population is concentrated around the LkH{alpha} 101 cluster and the filament extending from it. We present a quantitative description of the degree of clustering and discuss the relative fraction of YSOs in earlier (Class I and F) and later (Class II) classes compared to other clouds. We perform simple SED modeling of the YSOs with disks to compare the mid-IR properties to disks in other clouds and identify 14 classical transition disk candidates. Although the AMC is similar in mass, size, and distance to the OMC, it is forming about 15-20 times fewer stars.2014ApJ...786...37Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/786/37CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/680/495 : Survey of Interstellar clouds in the Gould beltJ/ApJS/185/198 : The Cepheus flare observed with IRAC and MIPS (Kirk+, 2009)J/ApJS/194/43 : YSOs candidates and knots in CrA cloud (Peterson+, 2011)J/ApJ/764/133 : Auriga-California giant molecular cloud (Harvey+, 2013)J/ApJS/220/11 : SEDs of Spitzer YSOs in the Gould Belt (Dunham+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/786/37https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/786/37http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/786/37https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/786/37https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/786/37http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/786/37GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/786/37/sample (YSOs (table 4) and YSO Candidates (table 5)in the AMC Based on WISE and MIPS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/786/37/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/786/37/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/786/37/sample?GETtext/xml+votable180.050000true60.352291741.03027780.0055555555555555565/401 6/1231 1242 1253 1261 1262 1263 1264 1266 1272 1274 1613 1636https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/786/37?format=asciiInfrareddefaultJ/ApJ/786/37/sampleYSOs (table 4) and YSO Candidates (table 5)in the AMC Based on WISE and MIPS_DEPosition from Name (declination part)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
