cds-question@unistra.frgiant-starsradio-astronomyWe present a compendium of HI 21-cm line observations of circumstellar envelopes (CSEs) of 290 evolved stars, mostly (~84%) on the asymptotic giant branch (AGB), made with the 100 m-class, single-dish Nancay Radio Telescope. The observational and data reduction procedures were optimised to separate genuine CSE HI emission from surrounding Galactic line features. For most targets (254), the results have not been previously published. Clear detections were made of 34 objects, for 33 of which the total HI flux and the size of the CSE could be determined. Possible detections were made of 21 objects, and upper limits could be determined for 95 undetected targets, while for 140 objects confusion from Galactic HI emission along the line of sight precluded meaningful upper limits. The collective results of this survey can provide guidance on the detectability of circumstellar HI gas for future mapping and imaging studies.2024A&A...692A..54Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/692/A54CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/692/A54https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/692/A54http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/692/A54https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/692/A54https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/692/A54http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/692/A54GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/692/A54/table6 (Confused NRT HI spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/692/A54/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/692/A54/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/692/A54/table6?GETtext/xml+votable180.050000true0.3160760.3552850.0055555555555555566/592 1102 1169 1238 1399 1727 1892 1986 2428 2500 2528 2602 2694 2920 2994 3026 3050 3359 3367 3438 3459 3640 3801 4347 4355 4365 4614 5489 6219 6714 6919 7673 8532 8573 8926 9074 9258 9639 9813 9968 10103 10107 10635 12770 12882 12953 13207 13297 13392 13677 13711 13968 13995 14447 14457 14674 14809 14853 14878 14894 14906 15170 15196 15401 15593 15641 16132 16157 16233 17357 19112 19847 20212 20598 21215 21224 21326 21523 21638 22016 22051 22093 22239 22806 22941 23488 23611 23850 23995 24151 24158 24164 24500 25228 25246 25489 25708 25798 25805 25842 26070 26180 27519 27788 29057 29286 29690 29832 29886 30011 30212 30221 30244 30448 30606 30661 30777 31828 32309 34576 34792 36028 36124 36222 36738 38862 39905 40244 40246 42730 42840 42895 42956 43890 44248 44417 44554 44857 46938 49132https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/692/A54?format=asciiRadiodefaultJ/A+A/692/A54/table6Confused NRT HI spectraSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
