cds-question@unistra.frmagellanic-cloudsmilky-way-galaxygiant-starssupergiant-starsinfrared-sourcesWe investigate the occurrence of crystalline silicates in oxygen-rich evolved stars across a range of metallicities and mass-loss rates. It has been suggested that the crystalline silicate feature strength increases with increasing mass-loss rate, implying a correlation between lattice structure and wind density. To test this, we analyse Spitzer Infrared Spectrograph and Infrared Space Observatory Short Wavelength Spectrometer spectra of 217 oxygen-rich asymptotic giant branch and 98 red supergiants in the Milky Way, the Large and Small Magellanic Clouds, and Galactic globular clusters. These encompass a range of spectral morphologies from the spectrally rich which exhibit a wealth of crystalline and amorphous silicate features to 'naked' (dust-free) stars. We combine spectroscopic and photometric observations with the GRAMS grid of radiative transfer models to derive (dust) mass-loss rates and temperature. We then measure the strength of the crystalline silicate bands at 23, 28 and 33{mu}m. We detect crystalline silicates in stars with dust mass-loss rates which span over 3dex, down to rates of ~10^-9^M_{sun}_/yr. Detections of crystalline silicates are more prevalent in higher mass-loss rate objects, though the highest mass-loss rate objects do not show the 23-{mu}m feature, possibly due to the low temperature of the forsterite grains or it may indicate that the 23-{mu}m band is going into absorption due to high column density. Furthermore, we detect a change in the crystalline silicate mineralogy with metallicity, with enstatite seen increasingly at low metallicity.2012MNRAS.427.3209Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/427/3209CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/427/3209https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/427/3209http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/427/3209https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/427/3209https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/427/3209http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/427/3209GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/427/3209/table2 (Details of the sources in the LMC sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/3209/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/3209/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/3209/table2?GETtext/xml+votable180.050000true70.1187083-69.92019440.005555555555555556Cone search capability for table J/MNRAS/427/3209/table3 (Details of the sources in the SMC sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/3209/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/3209/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/3209/table3?GETtext/xml+votable180.050000true8.0079167-73.37611110.005555555555555556Cone search capability for table J/MNRAS/427/3209/table4 (Details of the sources in the Galatic ISO/SWS sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/3209/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/3209/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/3209/table4?GETtext/xml+votable180.050000true3.8424167-32.04538890.005555555555555556Cone search capability for table J/MNRAS/427/3209/table5 (Details of the sources in the Galactic Spitzer IRS sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/3209/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/3209/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/3209/table5?GETtext/xml+votable180.050000true14.11837560.78590280.005555555555555556Cone search capability for table J/MNRAS/427/3209/table6 (Details of the sources in the globular cluster sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/3209/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/3209/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/3209/table6?GETtext/xml+votable180.050000true15.8129167-70.84230560.0055555555555555565/8269 8273-8275 8280 6/676 1889 1977 1986 3024 3030 3253 3256-3257 3262 3272 3362 3640 8532 8926 9137 9142 9939 10107 12321 12943 12965 13666 13813 13845 14196 14236 14253 14288 14302 14336 14357 14619 14623 14644 14674 14689 14834 15640 15650 16459 17716 18364 18998 23611 24178 25798 28705 28708 28713 28741 28766 28787 28789 28807 28826 28845 28875 28899 28905 28917 29249 29260 29285 29294 29528 29637 29817 29870 30011 30034 30087 30222 30244 30260 30313 30321 30445 30476 30606 30614 30625 31564 31828 31832 32083 32254 32259 32661 33047 33052-33053 33073 33081 33089-33091 33107 33110 33112-33113 33115 33124-33125 33127 33137 33294-33295 33299 33304 33306 33316-33317 33319 33328 33330 33689 36028 37813 38016 38053 41118 41727 41852 42213 42278 42314 42336 42396 42442 42489 42513 42833 42956 43227 43890 45782 45987 46330 48650https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/427/3209?format=asciiInfrareddefaultJ/MNRAS/427/3209/table2Details of the sources in the LMC sampleSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
