cds-question@unistra.frvariable-starschemical-abundancesWe propose a statistical method for decomposition of contributions to iron production from various sources: Type II supernovae and the subpopulations of Type Ia supernovae, prompt (their progenitors are short-lived stars with ages lower than >100Myr) and tardy (their progenitors are long-lived stars with ages >100Myr). To do that, we develop a theory of oxygen and iron synthesis that takes into account the influence of the spiral arms on the amount of the above elements synthesized by both Type II supernovae and prompt Type Ia supernovae. In the framework of the theory, we processed statistically the new, more precise, observational data on Cepheid abundances, which, as is well known, demonstrate non-trivial radial distributions of oxygen and iron in the Galactic disc with bends in the gradients.2012MNRAS.420.1590Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/420/1590CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/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/MNRAS/420/1590https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/420/1590http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/420/1590https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/420/1590https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/420/1590http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/420/1590GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/420/1590/tablea1 (Abundances, distances, ages and masses for classical Cepheids)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/420/1590/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/420/1590/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/420/1590/tablea1?GETtext/xml+votable180.050000true143.4619119-36.61576280.0055555555555555565/9482 6/1239 1340 1348 1388 1426 1429 1431-1432 1441 1445 1467 1765 1836 1858 1920 2805 3000 3005 3033 3045 3047 3052 3239 3263 3285 3309 3342 3361-3362 3365 3600 3616 3641 3849 4095 12321 12934 12971 13166 13201 13288 13309-13310 13931 13933 13961 13990 14009 14047 14205 14238-14239 14260 14262 14265 14271 14283 14295 14303 14328 14404 14409 14436 14469 14533 14601 14625 14637 14709 14718 14770 15360 15425 15618 15633 15660 21514 21542 21648 21671 21683 21686 22020 22044 22064 22068-22069 22071 22074 22106 22115-22116 22122 22124 22169 22214 22219 22221 22227 22267 22438 23619 23622 23635 23660 23662 23778 23841 23846 23852 23922 23936 24002 24146 24153 24226 24326 24372 24411 24450 24453 24478-24479 28717 28779 28808 28819 28893 28916 28991 29032 29081 29089 29095 29104 29110 29126 29166 29216 29523 29533 29665 29772 29875 29897 29999 30128 30211 30219 30222 30321-30322 30333 30438 30580 30609 30641 32012 32074 33804 37203 37223 37235 37273 37303 37330 37332 37334 37336 37340 37357 37364 37674 37713 37721 37723 37729 37741 37745-37746 37757 37828-37829 37856 37867 37870 37888 37903-37904 37917 37923 37926-37927 37938 37963 38020 38022-38023 38026 38029 38049 38627 39125 39216-39217 39231-39232 39244 39348 39374 39410 39766 39771 39790 39796 39883 39886 39889 39892 39920 39926 39933 39935 40580 40608 41375 41383 41385 41461 41556 41599 41605 41608 41631 41667 41681 41697-41698 41721-41722 41737 41761-41762 41810 41813 41842 41862 42153 42156 42185 42297 42352 42378 42500 42820 43013 43022 43028 43041 43047 43056-43057 430603.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/420/1590?format=asciiOpticaldefaultJ/MNRAS/420/1590/tablea1Abundances, distances, ages and masses for classical CepheidsNameCepheid namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
