cds-question@unistra.frmillimeter-astronomysubmillimeter-astronomyinfrared-photometrystellar-massesyoung-stellar-objectsWe present ALMA observations of the Orion Nebula that cover the OMC1 outflow region. Our focus in this paper is on compact emission from protoplanetary disks. We mosaicked a field containing ~600 near-IR-identified young stars, around which we can search for sub-millimeter emission tracing dusty disks. Approximately 100 sources are known proplyds identified with the Hubble Space Telescope. We detect continuum emission at 1mm wavelengths toward ~20% of the proplyd sample, and ~8% of the larger sample of near-IR objects. The noise in our maps allows 4{sigma} detection of objects brighter than ~1.5mJy, corresponding to protoplanetary disk masses larger than 1.5M_J_ (using standard assumptions about dust opacities and gas-to-dust ratios). None of these disks are detected in contemporaneous CO(2-1) or C^18^O(2-1) observations, suggesting that the gas-to-dust ratios may be substantially smaller than the canonical value of 100. Furthermore, since dust grains may already be sequestered in large bodies in Orion Nebula cluster (ONC) disks, the inferred masses of disk solids may be underestimated. Our results suggest that the distribution of disk masses in this region is compatible with the detection rate of massive planets around M dwarfs, which are the dominant stellar constituent in the ONC.2016ApJ...826...16Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/826/16CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/814/130 : Planet occurrence rates calculated for KOIs (Mulders+, 2015)J/A+A/579/A130 : Near-IR BN/KL outflow images (Bally+, 2015)J/ApJ/802/77 : Protoplanetary disk masses in NGC 2024 cluster (Mann+, 2015)J/ApJ/782/8 : Spectroscopy of 104 objects in the ONC (Ingraham+, 2014)J/MNRAS/435/1671 : SCUBA-2 850um survey in {sigma}Ori cluster (Williams+, 2013)J/AJ/146/85 : Spectral types of optical stars in ONC (Hillenbrand+, 2013)J/ApJ/771/129 : Submillimetric Class II sources of Taurus (Andrews+, 2013)J/PASP/123/412 : Exoplanet Orbit Database (Wright+, 2011)J/ApJ/697/1103 : Kinematics of Orion Nebula Cluster (Tobin+, 2009)J/AJ/136/2136 : HST/ACS Atlas of Great Orion Nebula proplyds (Ricci+, 2008)J/ApJ/671/1800 : SCUBA observations of {rho} Oph cloud (Andrews+, 2007)J/A+A/441/195 : Circumstellar disks in Trapezium cluster (Vicente+, 2005)J/ApJ/540/1016 : K-band+NICMOS photometry of Trapezium Cluster (Luhman+, 2000)J/ApJ/540/236 : KH photometry of Orion Nebula Cluster (Hillenbrand+, 2000)J/AJ/116/1816 : JHKLMNOPQ photometry in Orion cluster (Hillenbrand+, 1998)J/AJ/113/1733 : Orion Nebula Cluster population (Hillenbrand 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/826/16https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/826/16http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/826/16https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/826/16https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/826/16http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/826/16GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/826/16/table1 (New near-IR sources detected in GeMS imaging)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/826/16/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/826/16/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/826/16/table1?GETtext/xml+votable180.050000true83.8039583-5.37898330.005555555555555556Cone search capability for table J/ApJ/826/16/table3 (Fluxes observed toward non-detected source positions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/826/16/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/826/16/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/826/16/table3?GETtext/xml+votable180.050000true83.785125-5.35550.005555555555555556Cone search capability for table J/ApJ/826/16/table2 (Fluxes and inferred disk masses for ALMA-detected sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/826/16/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/826/16/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/826/16/table2?GETtext/xml+votable180.050000true83.7872083-5.3750.0055555555555555566/214391.528037907652962e-22 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/826/16?format=asciiInfraredMillimeterdefaultJ/ApJ/826/16/table1New near-IR sources detected in GeMS imagingrecnoRecord number assigned by the VizieR team.
