cds-question@unistra.frmultiple-starslate-type-starsm-starsdwarf-starschemical-abundancesDetailed chemical composition of stars is of prime interest for a range of topics in modern stellar astrophysics, such as the chemical evolution of the Galaxy or the formation, composition, and structure of exoplanets. In this work, we derive the C and O abundances and update Sc, V, Mn, and Co abundances considering hyperfine structure effects (HFS) and correcting for non-local thermodynamical equilibrium (NLTE) for a sample of 196 late-F, G-, and early-K stars with wide resolved M-dwarf companions. We accomplished this by employing the equivalent width (EW) method and high-resolution spectroscopic data. Furthermore, we investigated the distributions of [X/Fe] ratios and [C/O] as a function of metallicity ([Fe/H]) and kinematic population. The observed trends are consistent with previous findings reported in the literature. Additionally, we searched for confirmed exoplanets around our primary stars in the literature and found 24 exoplanets in 17 systems, while none of the M-dwarf companions in our sample presented confirmed exoplanets. In conclusion, our study provides homogeneous abundances from high-resolution spectra for a large sample of FGK primary stars, paving the way for further research on stellar abundances of the M secondaries and exoplanetary science.2024MNRAS.528.3028Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/528/3028CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)J/MNRAS/479/1332 : Binaries with F, G or K primaries & M dwarfs (Montes+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/528/3028https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/528/3028http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/528/3028https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/528/3028https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/528/3028http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/528/3028GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/528/3028/tablea1 (Abundances [X/H] with respect to the Sun)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/528/3028/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/528/3028/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/528/3028/tablea1?GETtext/xml+votable180.050000true3.8116666753.074166670.0055555555555555566/79 137 404 721 798 815 824 1063 1547 1591 1597 1692 1694 1762 1779 1788 1875 1888 2205 2754 2978 3020 3118 3313 4128 4145 4161 4388 4591 4702 4808 4879 4881 5009 5154 5304 5466 5587 5677 5948 6066 6662 6701 7354 7361 7382 7665 7677 7753 7831 7925 7978 8093 8168 8357 8381 8584 8609 8814 9024 9442 9580 9801 9888 10062 10515 10790 10814 11010 11276 11309 11385 11391 11403 11455 11546 11734 11810 11910 12108 12446 12856 12890 12983 13282 13311 13401 13475 13766 13772 13931 13938 14089 14144 14252 14419 14814 14850 15014 15813 16046 16056 16220 17341 17453 17496 17655 17825 17946 18003 18112 18379 18775 18974 19312 19323 19658 19778 19836 20261 20402 21047 21060 21477 21696 21726 22040 22162 22172 22252 22708 22878 22903 22995 23018 23137 23213 23401 23540 23575-23576 23738 24227 24299 24858 25192 25660 25728 25795 25880 26015 26128 26440 26522 26690 26706 26924 27678 27798 27802 27895 27910 27973 28074 28258 28421 29756 30529 30576 30939 31011 31358 31397 31425 31501 31860 32224 32324 32537 32575 32645 32656 36454 40679 40787 44025 44284 44530 44613 44891 48497 48530 48883https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/528/3028?format=asciidefaultJ/MNRAS/528/3028/tablea1Abundances [X/H] with respect to the SunSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
