cds-question@unistra.frsurveyssubdwarf-starsstellar-atmosphereschemical-abundancesWe present an update of our low-resolution spectroscopic follow-up and model atmosphere analysis of hot subdwarf stars from the Galaxy Evolution Explorer (GALEX) survey. Targets were selected on the basis of colour indices calculated from the GALEX GR6 N_UV_, Guide Star Catalogue (GSC2.3.2) Vand the Two Micron All Sky Survey (2MASS) J and H photometry. High signal-to-noise ratio spectra were obtained at the European Southern Observatory (ESO) and the Kitt Peak National Observatory (KPNO) over the course of three years. Detailed H, He and CNO abundance analysis helped us improve our T_eff_, logg and He abundance determination and to constrain CNO abundances. We processed 191 observations of 180 targets and found 124 sdB and 42 sdO stars in this sample while some blue horizontal branch stars were also found in this programme. With quantitative binary decomposition of 29 composite spectra we investigated the incidence of A, F and G type companions. The incidence of late G and K type companions and their effects on subdwarf atmospheric parameters were also examined.2012MNRAS.427.2180Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/427/2180CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/427/2180https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/427/2180http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/427/2180https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/427/2180https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/427/2180http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/427/2180GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/427/2180/table2 (Atmospheric parameters of hot subdwarf stars in the GALEX survey (Single stars and primaries))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/2180/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/2180/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/2180/table2?GETtext/xml+votable180.050000true8.8832524.98811110.005555555555555556Cone search capability for table J/MNRAS/427/2180/table2b (Atmospheric parameters of hot subdwarf stars in the GALEX survey (Companions))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/2180/table2b?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/2180/table2b?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/2180/table2b?GETtext/xml+votable180.050000true11.99841673.62855560.005555555555555556Cone search capability for table J/MNRAS/427/2180/table3 (Other targets that are not part of the GALEX UV selection (Single stars and primaries))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/2180/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/2180/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/2180/table3?GETtext/xml+votable180.050000true109.195541723.32502780.005555555555555556Cone search capability for table J/MNRAS/427/2180/table3b (Other targets that are not part of the GALEX UV selection (Companions))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/427/2180/table3b?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/427/2180/table3b?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/427/2180/table3b?GETtext/xml+votable180.050000true109.195541723.32502780.0055555555555555566/215 550 723 762 764 2039 2094 2424 2540 2616 2843 3092 4164 4233 4278 4285 4295 4345 4624 4630 4653 4658 4697 4704 4739 4790 4902 4976 5944 6060 6174 6178 6246-6247 6975 7004 7023 7052 7626 7670 7719 7729 7811 7903 8004 8447 9215 9273 9283 9429 9470 9640 9695 9812 9899 10007 10112 10333 10629 10810 11194 11479 11560 11634 11637 11682 11901 12234 12254 12302 12353 12443 12469 12505 12528 12569 12672 12721 12746 12912 13312 13319 13434 13651 13712 16346 16379 16430 17774 17918 18125 18222 18346 19361 19419 19451 19741 19801-19802 19905 19942 19993 20130 20363 20410 20474 21000 21585 21803 21991 22009 22344 22351 23009 23133 23385 23933 24529 25136 25318 25957 26229 26433 26436 26453 26735 27324 27486 27978 28323 28577 29738 30062 30109 30148 30155 30193 30196 30551 31444 31549 31560 31627 31640 31772 31821 31826 31880 31884 32330 32643 32652 32675 32749 34699 35258 36844 37389 38610 38832 40227 40714 41375 42256 43297 43860 44218 45443 46079 46228 46304 46798 46990 47304 47453 47722 47829 48310 48692 48915https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/427/2180?format=asciidefaultJ/MNRAS/427/2180/table2Atmospheric parameters of hot subdwarf stars in the GALEX survey (Single stars and primaries)SimbadNameSimbad column added by the CDSmeta.idcharComComments (1)meta.notecharrecnoRecord number assigned by the VizieR team.
