cds-question@unistra.frlate-type-starschemical-abundancesspectroscopyWe present fundamental stellar parameters, chemical abundances, and rotational velocities for a sample of 86 evolved stars with planets (56 giants; 30 subgiants), and for a control sample of 137 stars (101 giants; 36 subgiants) without planets. The analysis was based on both high signal-to-noise and resolution echelle spectra. The main goals of this work are i) to investigate chemical differences between evolved stars that host planets and those of the control sample without planets; ii) to explore potential differences between the properties of the planets around giants and subgiants; and iii) to search for possible correlations between these properties and the chemical abundances of their host stars. Implications for the scenarios of planet formation and evolution are also discussed. The fundamental stellar parameters (T_eff_, logg, [Fe/H], {xi}_t_) were computed homogeneously using the FUNDPAR code. The chemical abundances of 14 elements (Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Zn, and Ba) were obtained using the MOOG code. Rotational velocities were derived from the full width at half maximum of iron isolated lines. In agreement with previous studies, we find that subgiants with planets are, on average, more metal-rich than subgiants without planets by ~0.16dex. The [Fe/H] distribution of giants with planets is centered at slightly subsolar metallicities and there is no metallicity enhancement relative to the [Fe/H] distribution of giants without planets. Furthermore, contrary to recent results, we do not find any clear difference between the metallicity distributions of stars with and without planets for giants with M_*_>1.5M_{sun}_. With regard to the other chemical elements, the analysis of the [X/Fe] distributions shows differences between giants with and without planets for some elements, particularly V, Co, and Ba. Subgiants with and without planets exhibit similar behavior for most of the elements. On the other hand, we find no evidence of rapid rotation among the giants with planets or among the giants without planets. Finally, analyzing the planet properties, some interesting trends might be emerging: i) multi-planet systems around evolved stars show a slight metallicity enhancement compared with single-planet systems; ii) planets with a<~0.5AU orbit subgiants with [Fe/H]>0 and giants hosting planets with a<~1AU have [Fe/H]<0; iii) higher-mass planets tend to orbit more metal-poor giants with M_*_<=1.5M_{sun}_, whereas planets around subgiants seem to follow the planet-mass metallicity trend observed on dwarf hosts; iv) [X/Fe] ratios for Na, Si, and Al seem to increase with the mass of planets around giants; v) planets orbiting giants show lower orbital eccentricities than those orbiting subgiants and dwarfs, suggesting a more efficient tidal circularization or the result of the engulfment of close-in planets with larger eccentricities.2015A&A...574A..50Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/574/A50CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/574/A50https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/574/A50http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/574/A50https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/574/A50https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/574/A50http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/574/A50GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/574/A50/stars (Stars observed: Fundamental parameters (table2), photometric and evolutionary parameters (table 5) abundances (tables 6 and 7), and kinematics (table9))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/574/A50/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/574/A50/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/574/A50/stars?GETtext/xml+votable180.050000true4.821108614.05475390.0055555555555555566/341 679 737 1186 1249 1790 1819 2416 2440 2541 2577 3026 3094 3118 3619 4285 4429 4444 4839 4969 5059 5101 5815 6219 6361 6933 7113 7320 7760 8080 8756 8845 9061 9213 9610 9753 10256 10354 11473 11659 11734 12186 12306 12482 12612 12768 13333 13643 13731 14005 14013 14220 14329 14416 14434 14466 14604 14630 14767 15273 16023 16035 16213 16667 16679 17266 17394 17496 17568 17606 17723 17730-17731 17764 18102 18172 18276 18441 18466 18688 18953 18966 19669 19815 20015 20072 20308 20886 20981 21003 21050 21223 21233 21406 21423 21469 21531 21612 21627 21738 21806 21940-21941 22199 22330 22518 22878 22969 23048 23097 23230 23322 23533 23538 23547 23695 23711 24262 24877 24921 25114 25608 26120 26552 26575 26704 26707 26938 27040 27060 27220 27752 28044 28085 28276 28436 29291 29521 29589 30170 30278 30339 30419 30529 30541 30665 30770 30989 31428 31813 31842 31984 32158 32328 32348 32501 32645 33228 33243 33281 33377 33822 34169 34199 34288 34461 34510 34730 34773 35673 36035 36092 36115 36224 36433 36689 36693 36714 36723 36759 36784 37786 38630 39280 39446 39675 39926 40408 40795 40999 41154 41627 42113 42177 42281 42318 42383 42602 42686 42769 42956 43022 43046 43639 43893 44015 44518 44883 45050 45143 45865 46112 46775 47067 47078 47263 47590 48108-48109 48175 48572 48694 48955https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/574/A50?format=asciiOpticaldefaultJ/A+A/574/A50/starsStars observed: Fundamental parameters (table2), photometric and evolutionary parameters (table 5) abundances (tables 6 and 7), and kinematics (table9)NameStar namemeta.id;meta.maincharInstInstrument (1)meta.id;instrchare_Teff[9/61] rms uncertainty on TeffKstat.error;phys.temperature.effectiveintvsini[0.3/13] Rotational velocitykm/sphys.veloc.rotatfloat[CrII/H]Abundance [CrII/H]log(Sun)phys.abundfloatrecnoRecord number assigned by the VizieR team.
