cds-question@unistra.frcarbon-starsstellar-mass-lossinfrared-sourcesstellar-distanceAGB mass-losing sources are easy to identify and to characterize in the near-infrared range (1-5{mu}m). We make use of the near-infrared data acquired by the Japanese space experiment IRTS to study a sample of sources detected in the 2 celestial strips surveyed by the IRTS. Mass-loss rates and distances are estimated for 40 carbon-rich sources and 86 oxygen-rich sources of which 8 are probably of S-type. Although the sample is small, one sees a dependence of the relative contribution of the two kinds of sources to the replenishment of the interstellar medium (ISM) on the galactocentric distance. E.g. from 6 to 8kpc, oxygen-rich sources in our sample contribute 10-12 times as much as carbon rich sources, whereas from 10 to 12kpc, the latters contribute 3-4 times as much as the formers. Therefore, one would expect a gradient in the composition of the ISM between 6 and 12kpc from the Galactic Centre, especially in its dust component. Most of the replenishment (>50%) by AGB stars is due to sources with mass-loss rate larger than 10^-6^M_{sun}_/yr.2001A&A...376..997Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/376/997CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/376/997https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/376/997http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/376/997https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/376/997https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/376/997http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/376/997GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/376/997/table4 (Properties of the 126 selected mass-losing AGB sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/376/997/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/376/997/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/376/997/table4?GETtext/xml+votable180.050000true19.92487572.6109170.0055555555555555566/1285 1297 1306 1378 1504 1841 1844 1965 3364 3459 3465 3498 3793 3801 3852 4614 4632 11928 14894 14940 15170 15846 15939 16144 20811 20824 20838 20843 20857 20862-20863 21317 21338 21542 21545 21549 21656 21710 21732 21897 23559 23603 24158 24188 24191 24353 24361 24474 24496 28803 28834 28860 28906 29249 29251 29261 29269 29473 29475 29477 29550 29635 29637 29656 29963 30087 30091 30481 30484 30517 30521 30523 30538 30614 30659 30696 31766 31811 31834 32074 32077 32080 32110 32126 32198 32723 33919 34077 34118 34145 37139 37176 39163 41209 41388 41392 41394 41479 41492 41494 41501 41540 42141 42144 42185 42187 42199 42205 42362 42371 42384 42396 42438-42439 42447 42463 42485 46642 46768 48133 48715 48860 48869https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/376/997?format=asciiInfrareddefaultJ/A+A/376/997/table4Properties of the 126 selected mass-losing AGB sourcesIRASIRAS namemeta.idcharrecnoRecord number assigned by the VizieR team.
