The Spitzer Infrared Spectrograph (IRS) collected numerous spectra of various objects and provided a big database to investigate crystalline silicates in a wide range of astronomical environments. We apply the manifold ranking algorithm to perform a systematic search for the spectra with crystalline silicate features in the Spitzer IRS Enhanced Products available. In total, 868 spectra of 790 sources are found to show the features of crystalline silicates. These objects are cross-matched with the SIMBAD database as well as with the Large Sky Area Multi-object Fiber Spectroscopic Telescope (LAMOST)/DR2 (Luo et al. 2016, Cat. V/149). The average spectrum of young stellar objects shows a variety of features dominated either by forsterite or enstatite or neither, while the average spectrum of evolved objects consistently present dominant features of forsterite in AGB, OH/IR, post-AGB, and planetary nebulae. They are identified optically as early-type stars, evolved stars, galaxies and so on. In addition, the strength of spectral features in typical silicate complexes is calculated. The results are available through CDS for the astronomical community to further study crystalline silicates.2016AJ....151..146Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/151/146CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/149 : LAMOST DR2 catalogs (Luo+, 2016)J/A+A/382/184 : Crystalline silicates around evolved stars (Molster+, 2002)J/MNRAS/414/500 : Spitzer/IRS ATLAS project source (Hernan-Caballero+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/151/146https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/151/146http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/151/146https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/151/146https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/151/146http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/151/146GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/151/146/table7 (Results of cross-identification with LAMOST)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/151/146/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/151/146/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/151/146/table7?GETtext/xml+votable180.050000true45.5875717.176210.005555555555555556Cone search capability for table J/AJ/151/146/Results (Results of equivalent widths (table 3) , significance level and cristallinity (table 4) and SIMBAD type (table 5))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/151/146/Results?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/151/146/Results?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/151/146/Results?GETtext/xml+votable180.050000true12.68487-72.627650.0055555555555555565/292 5715 7590 8274 8275 8280 10283 10745 6/246 597 599 770 857 859 860 862 1029 1031 1037 1039 1040 1042 1043 1047 1050 1052 1054 1061 1073 1080 1081 1114 1124 1126 1156 1157 1159 1538 1539 2154 3024 3030 3069 3362 6845 7246 10806 12965 13283 14140 14306 14372 14687 15359 15363 15368 15410 15411 15478 15479 15486 15662 15683 15759 15798 15857 15965 16129 16189 16191 18741 18918 21274 21403 21425 21427 21428 21430 21435 21436 21438 21439 21456 21464 21480 22249 22801 22804 22805 22808 22844 22848 22851 22854 22855 22856 22859 22873 22875 22876 22881 22882 22884 22895 22905 23548 23549 23584 23637 23727 23738 23795 23810 23970 24178 24203 24277 24294 24299 24300 24449 24474 28708 28713 28724 28738 28741 28766 28778 28779 28787 28789 28819 28821 28823 28845 28849 28850 28852 28855 28895 28899 28905 28907 28909 28925 29087 29174 29187 29249 29260 29266 29285 29294 29335 29394 29463 29562 29915 29935 30219 30228 30271 30283 30321 30366 30476 30512 30621 30733 30741 30769 31564 31832 32068 32537 32956 33047 33052 33053 33054 33073 33074 33076 33078 33079 33081 33089 33090 33091 33092 33094 33095 33106 33107 33110 33112 33113 33115 33124 33127 33137 33294 33295 33304 33306 33317 33328 36946 36948 36956 36957 36958 36973 37012 37122 37128 37961 38450 38914 39163 39183 39282 39375 39389 39599 39753 41093 41126 41127 41130 41526 41639 41727 41784 41852 42011 42090 42336 42427 42429 42605 42610 42611 42614 42653 42704 42714 42736 42737 42823 42833 42869 42885 42941 42969 42970 42977 42989 42990 42992 42994 43000 43021 43227 43415 43416 44317 44356 44366 44367 44378 44379 44389 44401 44551 45987 47828 47845 47867 48879https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/151/146?format=asciiInfrareddefaultJ/AJ/151/146/table6Summary of SIMBAD TyperecnoRecord number assigned by the VizieR team.
