cds-question@unistra.frvariable-starschemical-abundancesThis paper reports on the spectroscopic investigation of 238 Cepheids in the northern sky. Of these stars, about 150 are new to the study of the galactic abundance gradient. These new Cepheids bring the total number of Cepheids involved in abundance distribution studies to over 400. In this work, we also consider systematics between various studies and also those which result from the choice of models.2011AJ....142..136Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/136CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+ 2007-2012)J/A+A/476/73 : Calibration of Cepheid Period/Luminosity relation (Fouque+ 2007)J/AJ/132/902 : Abundances of 54 Cepheids (Luck+, 2006)J/AJ/142/51 : Galactic Cepheids abundance variations (Luck+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/142/136https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/142/136http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/142/136https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/142/136https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/142/136http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/142/136GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/142/136/table4 (Average [x/H] ratios for Cepheids)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/142/136/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/142/136/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/142/136/table4?GETtext/xml+votable180.050000true292.3390011-7.04408610.0055555555555555565/9482 6/1239 1331 1340 1348 1388 1402 1411 1421 1426 1429 1431 1432 1441 1445 1467 1625 1631 1765 1824 1829 1836 1858 1920 1935 1985 3008 3022 3033 3050 3052 3054 3059 3060 3063 3131 3157 3182 3252 3255 3261 3263 3284 3285 3304 3306 3322 3328 3336 3337 3342 3361 3362 3365 3459 3589 3599 3600 3601 3627 3629 3631 3632 3645 3656 3663 3682 3712 3713 3714 3722 3728 3731 12436 12685 12846 12963 12968 12970 12971 13933 14047 14059 14075 14199 14212 14229 14238 14239 14246 14251 14260 14262 14267 14282 14291 14292 14295 14301 14314 14317 14320 14321 14323 14324 14329 14407 14409 14411 14424 14427 14430 14445 14449 14453 14455 14457 14469 14602 14607 14625 14629 14630 14634 14640 14653 14690 14698 14736 15378 15388 15392 15393 15396 15429 15461 15585 15632 15633 15639 15698 21632 21671 21679 21683 21686 22020 22044 22064 22068 22069 22071 22074 22106 22115 22116 22122 22124 22149 22169 22207 22210 22214 22219 22221 22223 22227 22255 22267 22438 23622 23635 23669 23670 23762 23778 23816 23841 23846 23852 23922 24002 24326 24340 24372 24411 24424 24450 24453 24478 24479 24527 24551 28808 29216 29533 29852 29897 29999 30211 30222 30223 30235 30245 30258 30265 30270 30307 30311 30321 30333 30504 30596 30641 30646 32012 32064 37203 37223 37235 37245 37268 37273 37330 37332 37334 37336 37340 37357 37364 37674 37713 37721 37723 37729 37741 37745 37757 37828 37829 37856 37867 37870 37888 37903 37904 37917 37923 37926 37927 37938 37963 38020 38022 38023 38026 38029 38049 38627 39125 39217 39231 39232 39244 39348 39374 39410 39766 39771 39790 39889 39892 39908 39926 39933 40580 41375 41383 41385 41461 41556 41599 41605 41608 41631 41667 41681 41697 41698 41721 41722 41737 41761 41762 41810 41813 41842 41862 42153 42156 42297 42352 42500 42820 43013 43022 43028 43041 43047 43056 43057 430603.403972620454305e-19 3.851122986302185e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/142/136?format=asciidefaultJ/AJ/142/136/table1Program starsrecnoRecord number assigned by the VizieR team.
