cds-question@unistra.fropen-star-clusterschemical-abundancesvisible-astronomyOpen clusters are ideal laboratories to investigate a variety of astrophysical topics, from the properties of the Galactic disc to stellar evolution models. For this purpose, we need to know their chemical composition in detail. Unfortunately, the number of systems with chemical abundances determined from high resolution spectroscopy remains small. Our aim is to increase the number of open clusters with radial velocities and chemical abundances determined from high resolution spectroscopy by sampling a few stars in clusters which had not been previously studied. We obtained high resolution spectra with the FIbre-fed Echelle Spectrograph at Nordic Optical Telescope for 41 stars belonging to 20 open clusters. These stars have high astrometric membership probabilities determined from the Gaia second data release. We derived radial velocites for all the observed stars which were used to confirm their membership to the corresponding clusters. For Gulliver 37, we cannot be sure the observed star is a real member. We derived atmospheric parameters for the 32 stars considered to be real cluster members. We discarded five stars because they have very low gravity or their atmospheric parameters were not properly constrained due to low signal-to-noise ratio spectra. Therefore, detailed chemical abundances were determined for 28 stars belonging to 17 clusters. For most of them, this is the first chemical analysis available in the literature. Finally, we compared the clusters in our sample to a large population of well-studied clusters. The studied systems follow the trends, both chemical and kinematical, described by the majority of open clusters. It is worth mentioning that the three most metal-poor studied clusters (NGC 1027, NGC 1750, and Trumpler 2) are enhanced in Si, but not in the other {\alpha}-elements studied (Mg, Ca, and Ti).2022A&A...663A.148Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/663/A148CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/663/A148https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/663/A148http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/663/A148https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/663/A148https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/663/A148http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/663/A148GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/663/A148/tableb2 (Effective temperatures, surface gravities, and global metallicities obtained from the spectroscopic analysis of the observed stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/663/A148/tableb2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/663/A148/tableb2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/663/A148/tableb2?GETtext/xml+votable180.050000true95.039710346.64687720.005555555555555556Cone search capability for table J/A+A/663/A148/tableb5 (Average abundances for the observed clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/663/A148/tableb5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/663/A148/tableb5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/663/A148/tableb5?GETtext/xml+votable180.050000true94.843203346.66245030.0055555555555555566/1655 1661 3009 3230 3252 3308 3596 6760 6762 6881 14322 14363 14388 20853 21633 22097 23580 23765 23936 24228 24230 24291 30124 30127 32111https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/663/A148?format=asciiOpticaldefaultJ/A+A/663/A148/tableb2Effective temperatures, surface gravities, and global metallicities obtained from the spectroscopic analysis of the observed starsSimbadNameSimbad column added by the CDSmeta.idcharnullablee_[Mn/H]Mn abundance over H errorstat.error;phys.abundfloatrecnoRecord number assigned by the VizieR team.
