cds-question@unistra.frpeculiar-variable-starschemical-abundanceseffective-temperatureWe present a spectroscopic survey of known and candidate {gamma} Doradus stars. The high-resolution, high signal-to-noise spectra of 52 objects were collected by five different spectrographs. The spectral classification, atmospheric parameters (T_eff_, logg, {xi}), vsini and chemical composition of the stars were derived. The stellar spectral and luminosity classes were found between G0-A7 and IV-V, respectively. The initial values for T_eff_ and logg were determined from the photometric indices and spectral energy distribution. Those parameters were improved by the analysis of hydrogen lines. The final values of T_eff_, logg and {xi} were derived from the iron lines analysis. The T_eff_ values were found between 6000K and 7900K, while log g values range from 3.8 to 4.5dex. Chemical abundances and vsin i values were derived by the spectrum synthesis method. The vsini values were found between 5 and 240km/s. The chemical abundance pattern of {gamma} Doradus stars were compared with the pattern of non-pulsating stars. It turned out that there is no significant difference in abundance patterns between these two groups. Additionally, the relations between the atmospheric parameters and the pulsation quantities were checked. A strong correlation between the vsini and the pulsation periods of {gamma} Doradus variables was obtained. The accurate positions of the analysed stars in the Hertzsprung-Russell diagram have been shown. Most of our objects are located inside or close to the blue edge of the theoretical instability strip of {gamma} Doradus.2016MNRAS.458.2307Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/2307CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/458/2307https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/2307http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/2307https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/2307https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/2307http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/2307GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/458/2307/table2 (Spectroscopic observations and the spectral classification of the investigated stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/2307/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/2307/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/2307/table2?GETtext/xml+votable180.050000true23.439492560.62310890.0055555555555555566/463 487 3097 3504 3622 5724 10950 11500 11770 11839 11917 11946 12282 12695 15019 17398 17404 21275 21927 22050 23273 24315 24612 24842 25685 25746 25955 26174 27091 27765 28490 28585 29774 30318 30458 31809 36220 37319 37789 42186 42677 43641 43914 44139 45449 45469 46126 46164 47392 47395 47638 49128https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/458/2307?format=asciidefaultJ/MNRAS/458/2307/table2Spectroscopic observations and the spectral classification of the investigated starsrecnoRecord number assigned by the VizieR team.
