cds-question@unistra.frmagellanic-cloudsinfrared-sourcesmillimeter-astronomysubmillimeter-astronomyTo ascertain the nature of the brightest compact mid-infrared (mid-IR) sources in the Large Magellanic Cloud (LMC), we have applied an updated version of Buchanan et al.'s (2006AJ....132.1890B) Two Micron All Sky Survey (2MASS)-Midcourse Space Experiment (MSX) color classification system, which is based on the results of Spitzer Space Telescope spectroscopy, to a mid-IR (8um) flux-limited sample of 250 LMC objects for which 2MASS and MSX photometry is available. The resulting 2MASS-MSX ("JHK8") color-based classifications of these sources, which constitute the most mid-IR-luminous objects in the LMC, were augmented, cross-checked, and corrected where necessary via a variety of independent means, such that only 46 sources retain tentative classifications and only 10 sources cannot be classified at all. The sample is found to consist primarily of carbon-rich asymptotic giant branch (AGB) stars (35%), red supergiants (RSGs) (18%), and compact HII regions (32%), with additional, small populations of oxygen-rich AGB stars (~5%), dusty, early-type emission-line stars (~3%), and foreground, O-rich AGB stars in the Milky Way (~3%).2008AJ....136.1221Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/136/1221CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003)J/AJ/122/1844 : MSX and 2MASS cross-correlation in LMC (Egan+, 2001)J/AJ/132/2268 : SAGE calibration stars (Meixner+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/136/1221https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/136/1221http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/136/1221https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/136/1221https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/136/1221http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/136/1221GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/136/1221/table1 (Objects in the A-band flux-limited 2MASS/MSX sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/136/1221/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/136/1221/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/136/1221/table1?GETtext/xml+votable180.050000true77.4315833-65.36644440.0055555555555555565/8263 8272 8274 8280 6/33037 33044 33046 33047 33059 33073 33075 33076 33078 33079 33080 33081 33087 33092 33094 33100 33101 33102 33105 33110 33111 33112 33113 33115 33116 33124 33126 33127 33136 33137 33792 33793 33794 33800 37536 37544 37546 38912 389141.9123168730464538e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/136/1221?format=asciiInfraredRadiodefaultJ/AJ/136/1221/table1Objects in the A-band flux-limited 2MASS/MSX samplerecnoRecord number assigned by the VizieR team.
