cds-question@unistra.frinfrared-photometrysupergiant-starsgiant-starsyoung-stellar-objectsgalaxiesinfrared-sourcesWe explore the stellar population of M31 in a Spitzer Space Telescope survey utilizing IRAC and MIPS observations. Red supergiants are the brightest objects seen in the infrared; they are a prominent evolutionary phase. Due to their circumstellar envelopes, many of these radiate the bulk of their luminosity at IRAC wavelengths and do not stand out in the near-infrared or optically. Going fainter, we see large numbers of luminous asymptotic giant branch stars (AGB), many of which are known long-period variables. Relative to M33 the AGB carbon star population of M31 appears sparse, but this needs to be spectroscopically confirmed.2008ApJ...687..230Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/687/230CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/132/271 : SFR of M31 from resolved stars in near-IR (Olsen+, 2006)J/ApJS/154/623 : M31 Long Period Variables : Photometry (Mould+, 2004)J/ApJS/118/177 : JHK photometry of M31 spiral arm (Kodaira+, 1998)J/AJ/96/1884 : BVRJHK photometry of M31 red supergiants (Humphreys+ 1988)http://irsa.ipac.caltech.edu/applications/Gator : NASA/IPAC catalogs onlinehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/687/230https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/687/230http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/687/230https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/687/230https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/687/230http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/687/230GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/687/230/table1 (Photometry of the infrared brightest stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/687/230/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/687/230/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/687/230/table1?GETtext/xml+votable180.050000true9.2034139.940460.005555555555555556Cone search capability for table J/ApJ/687/230/table2 (2MASS 6X matches)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/687/230/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/687/230/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/687/230/table2?GETtext/xml+votable180.050000true9.6290640.309040.005555555555555556Cone search capability for table J/ApJ/687/230/table3 (Long period variables (LPV) matches)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/687/230/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/687/230/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/687/230/table3?GETtext/xml+votable180.050000true10.1705840.381030.005555555555555556Cone search capability for table J/ApJ/687/230/table4 (MIPS 24 micron sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/687/230/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/687/230/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/687/230/table4?GETtext/xml+votable180.050000true9.8389840.361740.0055555555555555566/2619 2622 2623 2666 2667 2705 2708 2709 2710 27526.772611666688002e-21 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/687/230?format=asciiInfrareddefaultJ/ApJ/687/230/table1Photometry of the infrared brightest starsrecnoRecord number assigned by the VizieR team.
