cds-question@unistra.frlate-type-starsmetallicityspectroscopyWe report results from the high-resolution spectral analysis of the 107 metal-rich (mostly [Fe/H]>=7.67dex) target stars from the Calan-Hertfordshire Extrasolar Planet Search programme observed with HARPS. Using our procedure of finding the best fit to the absorption line profiles in the observed spectra, we measure the abundances of Na, Mg, Al, Si, Ca, Ti, Cr, Mn, Fe, Ni, Cu and Zn, and then compare them with known results from different authors. Most of our abundances agree with these works at the level of +/-0.05dex or better for the stars we have in common. However, we do find systematic differences that make direct inferences difficult. Our analysis suggests that the selection of line lists and atomic line data along with the adopted continuum level influence these differences the most. At the same time, we confirm the positive trends of abundances versus metallicity for Na, Mn, Ni and, to a lesser degree, Al. A slight negative trend is observed for Ca, whereas Si and Cr tend to follow iron. Our analysis allows us to determine the positively skewed normal distribution of projected rotational velocities with a maximum peaking at 3km/s. Finally, we obtained a Gaussian distribution of microturbulent velocities that has a maximum at 1.2km/s and a full width at half-maximum {Delta}v_1/2_=0.35km/s, indicating that metal-rich dwarfs and subgiants in our sample have a very restricted range in microturbulent velocity.2017MNRAS.468.4151Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/468/4151CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/275/101 : Chemical evolution of the galactic disk I (Edvardsson+ 1993)J/A+AS/129/237 : G and K dwarfs abundances (Feltzing+ 1998)J/ApJS/159/141 : Spectroscopic properties of cool stars I (Valenti+ 2005)J/A+A/485/571 : Abundance distribution of stars with planets (Jenkins+ 2008)J/A+A/531/A8 : Activity indexes and velocities for 890 stars (Jenkins+ 2011)J/A+A/545/A32 : Chemical abundances of 1111 FGK stars (Adibekyan+ 2012)J/A+A/552/A27 : Stellar activity and kinematics of FGK stars (Murgas+ 2013)J/A+A/562/A71 : Chemical abundances of solar neighbour dwarfs (Bensby+ 2014)J/A+A/577/A9 : Sc, V, Mn, and Co in Milky Way stars (Battistini+ 2015)J/ApJS/225/32 : Extended abundance analysis of cool stars (Brewer+ 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/468/4151https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/468/4151http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/468/4151https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/468/4151https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/468/4151http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/468/4151GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/468/4151/tablea2 (Parameters and abundances for all target stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/468/4151/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/468/4151/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/468/4151/tablea2?GETtext/xml+votable180.050000true16.990065-37.89815750.0055555555555555566/17288 17447 17453 17507 20586 20633 20842 21270 21809 24597 24618 24702 25168 25276 25378 25484 25904 26679 28779 28891 29043 30929 32986 33604 33731 33873 34073 34425 34586 34793 35109 35146 35452 35615 35668 35811 35839-35840 36816 36952 36954 37418 37482 37565 37955 38127 38324 38452 38757 38856 39213 39425 39433 39441 39446 39463 39516 39623 39722 39813 39954 40080 40143 40183 40741 42044 42197 42205 42212 42224 42360 42519 42527 42570 42794 42808 42892 43047 43124 43387 43659 44223 44652 45112 45505 45646 46009 46032 46100 46118 46200 46364 46394 46437 46544 46603 46784 47223 47409 47580 47842 47894 47994 48061 48238 48658 48773https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/468/4151?format=asciiOpticaldefaultJ/MNRAS/468/4151/tablea2Parameters and abundances for all target stars[Al/H]Neutral Al abundancelog(Sun)phys.abundfloatrecnoRecord number assigned by the VizieR team.
