cds-question@unistra.frmillimeter-astronomysubmillimeter-astronomyinterstellar-mediuminfrared-sourcesWe present the first results from a new 250, 350, and 500um Galactic plane survey taken with the Balloon-borne Large-Aperture Submillimeter Telescope (BLAST) in 2005. This survey's primary goal is to identify and characterize high-mass protostellar objects (HMPOs). The region studied here covers 4{deg}^2^ near the open cluster NGC 6823 in the constellation Vulpecula (l=59{deg}). We find 60 compact sources (<60" diameter) detected simultaneously in all three bands. Their SEDs are constrained through BLAST, IRAS, Spitzer MIPS, and MSX photometry, with inferred dust temperatures spanning ~12-40K assuming a dust emissivity index {beta}=1.5. The luminosity-to-mass ratio, a distance-independ ent quantity, spans ~0.2-130L_{sun}_/M_{sun}_. Distances are estimated from coincident ^13^CO(1-0) velocities combined with a variety of other velocity and morphological data in the literature. In total, 49 sources are associated with a molecular cloud complex encompassing NGC 6823 (distance ~2.3kpc), 10 objects with the Perseus arm (~8.5kpc), and one object is probably in the outer Galaxy (~14kpc). Near NGC 6823, the inferred luminosities and masses of BLAST sources span ~40-10^4^L_{sun}_ and ~15-700M_{sun}_, respectively. The mass spectrum is compatible with molecular gas masses in other high-mass star-forming regions. Several luminous sources appear to be ultracompact H II regions powered by early B stars. However, many of the objects are cool, massive gravitationally bound clumps with no obvious internal radiation from a protostar, and hence excellent HMPO candidates.2008ApJ...681..428Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/681/428CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/681/428https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/681/428http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/681/428https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/681/428https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/681/428http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/681/428GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/681/428/sources (Fluxes, positions, IRAS and Spitzer MIPS photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/681/428/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/681/428/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/681/428/sources?GETtext/xml+votable180.050000true294.6541723.094720.0055555555555555565/35881.6558465556080236e-21 2.1346512726771855e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/681/428?format=asciiInfraredRadiodefaultJ/ApJ/681/428/sourcesFluxes, positions, IRAS and Spitzer MIPS photometryrecnoRecord number assigned by the VizieR team.
