cds-question@unistra.frlate-type-starss-starsinfrared-sourcesinfrared-photometryPhotometric observations in the near infrared for 161 S stars, including 18 Tc-rich (intrinsic) stars, 19 Tc-deficient (extrinsic) ones and 124 candidates for Tc-deficient S stars, are presented in this paper. Based on some further investigations into the infrared properties of both Tc-rich and Tc-deficient S stars, 104 candidates are identified as very likely Tc-deficient S stars. The large number of infrared-selected Tc-deficient S stars provides a convenient way to study the physical properties and the evolutionary status of this species of S stars.2002A&A...387..129Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/387/129CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/168 : General Catalog of S Stars, second edition (Stephenson 1984)III/197 : IRAS Low Resolution Spectra (IRAS team, 1987)J/AZh/76/604 : Spectrophotometry of S and carbon stars (Tereshchenko, 1999)J/A+A/333/952 : BVRI photometry of HR 1105 (Adelman 1998)J/A+AS/113/51 : Catalogue of associations IRAS and S stars (Chen+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/387/129https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/387/129http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/387/129https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/387/129https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/387/129http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/387/129GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/387/129/table3 (Observed candidates for Tc-deficient S stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/387/129/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/387/129/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/387/129/table3?GETtext/xml+votable180.050000true8.23291763.9855560.005555555555555556Cone search capability for table J/A+A/387/129/table1 ({alpha}12 values of the S stars whose Tc contents are well known.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/387/129/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/387/129/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/387/129/table1?GETtext/xml+votable180.050000true1.9025-62.3150.0055555555555555566/460 469 694 1033 1064 1139 1380 1405 1420 1448 1506 1516 1531 1799 1820 1922 2056 2194 2305 2335 2500 2694 2773 2885 3061 3141 3153 3373 3432 3462 3468 3613 3648 3953 4146 4663 4748 4798 4972 6271 6312 6800 6919 7052 7533 7881 9589 9968 10159 11227 12440 12844 12857 12875 13010 13013 13089 13176 13205 13283 13287 13455 13521 13676 13711 13971 14029 14042 14051 14109 14132 14145 14147 14279 14457 14472 14593 14603 14620 14623 14631 14636 14659 14769 14822 14889 15107 15127 15170 15366 15369 15399 15430 15442 15448 15560 15600 16783 17178 18536 18878 18890 19284 19813 20102 20110 20271 20388 20950 20972 21258 21310 21363 21422 21484 21557 21580 21610 21631 21648 21659 21807 22014 22082 22099 22140 22189 22200 22204 22218 22257 22262 22276 22483 22497 22776 22901 23284 23423 23495 23595 23599 23687 23846 23910 23932 23937 23987 24030 24039 24050 24152 24365 24375 24418 24495 24497 24513 24605 25821 25887 25987 26701 27540 28690 29045 29145 29351 29421 29477 29751 29811 30011 30062 30110 30183 30302 30326 30379 30457 30488 30556 30649 30742 30859 31002 31046 31218 32136 32175 32211 32243 32384 32472 32911 34665 34848 40613 41965 45694 46318 48464 48766 48817https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/387/129?format=asciiInfrareddefaultJ/A+A/387/129/table3Observed candidates for Tc-deficient S starsF12um?
