cds-question@unistra.frinfrared-sourcesinfrared-photometrymillimeter-astronomyphotometrysubmillimeter-astronomyWe have identified 230 Tycho-2 Spectral Catalog stars that exhibit 8um mid-IR extraphotospheric excesses in the MSX and Spitzer GLIMPSE surveys. Of these, 183 are either OB stars earlier than B8 in which the excess plausibly arises from a thermal bremsstrahlung component or evolved stars in which the excess may be explained by an atmospheric dust component. The remaining 47 stars have spectral classifications B8 or later and appear to be main-sequence or late pre-main-sequence objects harboring circumstellar disks. Six of the 47 stars exhibit multiple signatures characteristic of pre-main-sequence circumstellar disks, including emission lines, near-IR K-band excesses, and X-ray emission. Approximately one-third of the remaining 41 sources have emission lines suggesting relative youth. We modeled the excesses in 26 stars having two or more measurements in excess of the expected photospheres as single-component blackbodies.2007ApJ...658.1264Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/658/1264CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/293 : GLIMPSE Source Catalog (I + II + 3D) (IPAC 2008)III/231 : The Tycho-2 Spectral Type Catalog (Wright+, 2003)V/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/658/1264https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/658/1264http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/658/1264https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/658/1264https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/658/1264http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/658/1264GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/658/1264/glimpse (Photometric parameters for stars observed by GLIMPSE (Cat.
