cds-question@unistra.frinfrared-photometryvisible-astronomybroad-band-photometryextinctionmilky-way-galaxystellar-associationsWe derive distance, density, and metallicity distribution of the stellar Monoceros Overdensity (MO) in the outer Milky Way, based on deep imaging with the Subaru Telescope. We applied color-magnitude diagram fitting techniques in three stripes at galactic longitudes, l~130{deg}, 150{deg}, 170{deg}, and galactic latitudes, +15{deg}<=b<=+25{deg}. The MO appears as a wall of stars at a heliocentric distance of ~10.1+/-0.5kpc across the observed longitude range with no distance change. The MO stars are more metal-rich ([Fe/H]~-1.0) than the nearby stars at the same latitude. These data are used to test three different models for the origin of the MO: a perturbed disk model, which predicts a significant drop in density adjacent to the MO that is not seen; a basic flared disk model, which can give a good match to the density profile but the MO metallicity implies the disk is too metal-rich to source the MO stars; and a tidal stream model, which, from the literature, brackets the distances and densities we derive for the MO, suggesting that a model can be found that would fully fit the MO data. Further data and modeling will be required to confirm or rule out the MO feature as a stream or as a flaring of the disk.2012ApJ...754..101Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/754/101CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/139 : The SDSS Photometric Catalog, Release 9 (Adelman-McCarthy+, 2012)J/MNRAS/419/2844 : RAVE-DR3 radial metallicity gradient (Coskunoglu+, 2012)J/ApJ/731/4 : Galactic halo as seen by the CFHTLS (Sesar+, 2011)J/ApJ/588/824 : Velocities of blue stars near (l,b)=(198,-27) (Yanny+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/754/101https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/754/101http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/754/101https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/754/101https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/754/101http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/754/101GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/754/101/mo130 (*The l=130{deg} stripe catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/754/101/mo130?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/754/101/mo130?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/754/101/mo130?GETtext/xml+votable180.050000true42.554833376.80666670.005555555555555556Cone search capability for table J/ApJ/754/101/mo150 (*The l=150{deg} stripe catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/754/101/mo150?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/754/101/mo150?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/754/101/mo150?GETtext/xml+votable180.050000true83.291458362.25633330.005555555555555556Cone search capability for table J/ApJ/754/101/mo170 (*The l=170{deg} stripe catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/754/101/mo170?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/754/101/mo170?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/754/101/mo170?GETtext/xml+votable180.050000true99.732291745.34488890.0055555555555555565/508 509 987 1716 1734 1736 1737 1791 1960 6/2011 2014 2041 3899 3902 3903 3945 3946 3947 3962 3963 3965 3966 3967 3988 3989 4032 4033 4036 4037 4048 4049 4052 4053 6775 6778 6779 6781 6782 6783 6854 6855 6868 6927 6930 6931 6933 6934 6935 6940 6952 6953 6954 6976 6978 7158 7159 7162 7163 7822 7823 7827 7830 7832 7833 7834 7836 7844 7845 7846 7848 8126 8127 8170https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/754/101?format=asciiOpticalInfrareddefaultJ/ApJ/754/101/mo130*The l=130{deg} stripe catalogrecnoRecord number assigned by the VizieR team.
