cds-question@unistra.frchemically-peculiar-starsastronomical-modelsstellar-atmospheresIn order to investigate the formation of O I 7771-5 and [O I] 6300/6363 lines, extensive non-LTE calculations for neutral atomic oxygen were carried out for wide ranges of model atmosphere parameters, which are applicable to early-K through late-F halo/disk stars of various evolutionary stages. The formation of the triplet O I lines was found to be well described by the classical two-level-atom scattering model, and the non-LTE correction is practically determined by the parameters of the line-transition itself without any significant relevance to the details of the oxygen atomic model. This simplifies the problem in the sense that the non-LTE abundance correction is essentially determined only by the line-strength (W_{lambda}_), if the atmospheric parameters of Teff, logg, and {xi} are given, without any explicit dependence of the metallicity; thus allowing a useful analytical formula with tabulated numerical coefficients. On the other hand, our calculations lead to the robust conclusion that LTE is totally valid for the forbidden [O I] lines.2003A&A...402..343Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/402/343CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/402/343https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/402/343http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/402/343https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/402/343https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/402/343http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/402/343GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/402/343/stars (Positions of stars in table5.dat (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/402/343/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/402/343/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/402/343/stars?GETtext/xml+votable180.050000true4.24833312.54750.0055555555555555566/12 154 373 747 798 1341 1556 1808 2500 2581 2923 3020 3049 3258 3494 3586 3604 3658 3755 3970 4079 4376 5266 5589 5622 6051 6058 6159 6226 6256 6792 7334 7710 7767 8210 8314 8354 9004 9503 9537 10336 10359 12095 12164 12295 12332 12424 12451 12621 12704 13028 13075 13354 13478 14151 14385 14534 14956 15481 16115 16412 16453 16513 16759 16821 16883 16912 16924 17047 17136 17224 17234 17245 17425 17509 17519 17582 17606 17695 17744 17782 18035 18364 18548 18615 18893 18990 19217 19579 19585 19626 19670 19853 19924 20244-20245 20278 20297 20333 20390 20739 21060 21269 21389 21809 21862 21864 21989 22120 22205 22558 22594 22654 22841 23011 23096 23177 23192 23201 24827 24924 24942 25051 25192 25444 25554 25569 25607 25862 26025 26109 26289 26302 26347 26366 26380 26457 27075 27857 27975 28336 28664 28763 28966 29136 29490 29548 29703 29731 29765 29769 30233 30577 30848 31048 31094 31132 31172 31503 31748 31757 32335 32343 32468 33211 33224 33273 33456 33545 33552 34171 34559 34994 35064 35080 35149 35323 35442 35666 35701 35742 35749 35768 35774 35836 36145 36221 36365 36517 36745 36762 37232 37585 37831 38072 38918 38966 38986 39490 39709 39926 40222 40337 40567 40716 40722 40950 41763-41764 41941 42253 42326 42331 42486 43001 43074 43127 43310 43445 43544 43595 43641 44180 44191 44208 44281 44542 44653 44771 45050 45353 45485 45668 45865 46022 46053 46506 46593 46793 46828-46829 46947 47126 47147 47377 47407 47596 47740 47876 48281 48367 48394 48501 48636 48719 48736 48798 48946 49106https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/402/343?format=asciidefaultJ/A+A/402/343/starsPositions of stars in table5.dat (from Simbad)BmagB magnitudemagphot.mag;em.opt.BfloatVmagV magnitudemagphot.mag;em.opt.VfloatStarStar namemeta.id;meta.maincharprimarySpTypeMK Spectral typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
