cds-question@unistra.frsolar-system-planetsstellar-atmosphereschemically-peculiar-starsWe present a uniform and homogeneous study of the abundances of Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Na, Mg and Al in 100 stars with and 94 without known planetary companions. The main purpose of this work is to make a deep investigation of the abundance of refractory elements, using an enlarged set of data which includes new observations, especially for the sample of stars without known planets. The new comparison sample spans metallicity range -0.70<[Fe/H]<0.50 and fills the gap that previously existed, mainly at high metallicities, in the number of field "single" comparison stars. Furthermore, we improved the line list previously studied by other authors: on average we analysed 90 spectral lines in every spectrum and carefully measured more than 16 600 equivalent widths (EW) to calculate the abundances. We investigate possible differences between the chemical abundances of the two groups of stars, with and without planets. The results are globally comparable to those obtained by other authors, and in most cases the abundance trends of planet-host stars are very similar to those of the comparison sample. This work represents a step towards the comprehension of recently discovered planetary systems. These results could also be useful for verifying galactic models at high metallicities and consequently improve our knowledge of stellar nucleosynthesis and galactic chemical evolution.2006A&A...449..723Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/449/723CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/415/1153 : [Fe/H] for 98 extra-solar planet-host stars (Santos+, 2004)J/A+A/384/879 : Galactic orbits of stars with planets (Barbieri+, 2002)J/A+A/356/590 : The CORALIE survey for extrasolar planets II (Udry+, 2000)J/A+A/375/205 : The CORALIE survey for extrasolar planets V (Naef+ 2001)J/A+A/379/999 : The CORALIE survey for extrasolar planets VI (Santos+ 2001)J/A+A/388/632 : The CORALIE survey for extrasolar planets VII (Pepe+, 2002)J/A+A/390/267 : The CORALIE survey for extrasolar planets VIII (Udry+, 2002)J/A+A/392/215 : The CORALIE survey for extrasolar planets IX (Santos+ 2002)J/A+A/415/391 : The CORALIE survey for extrasolar planets XII (Mayor+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/449/723https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/449/723http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/449/723https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/449/723https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/449/723http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/449/723GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/449/723/stars (Star positions and magnitudes (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/449/723/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/449/723/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/449/723/stars?GETtext/xml+votable180.050000true1.58-49.0752780.0055555555555555566/679 748 871 1597 2110 2472 4136 5009 5522 5718 6760 6831 7240 7746 8357 8843 9403 9843 11473 12030 12146 12644 12899 14416 14419 14466 14525 14548 15174 16213 16518 16652 17341 17425 17730 18614 18688 18748 18821 19904 19912 20145 20701 21177 21484 21691 21726 21838 21901 21912 22036 22040 22252 22518 22590 22708 22878 23013 23201 24019 24178 24713 24729 24777 24858 24924 25407 25939 26183 26575 27018 27750 27975 28130 28696 28763 28987 29084 29196 29513 29541 30015 30343 30878 30965 31011 31130 31374 31393 32848 32930 33243 33552 33630 33717 33813 33818 33923 34446 34508 34817 34896 34905 34951 35064 35079 35351 35362 35442 35753 35948 36288 36365 36664 36693 36697 37408 37461 37479 37573 37595 37909 38219 38238 38461 38545 38932 39154 39257 39280 39284 39500 39675 40007 40078 40101 40242 40442 40488 40692 40932 41446 41460 41463 41607 41612 41687 41724 41763 41941 42022 42248 42285 42333 42426 42459 42510 42595 42700 42760 42845 43012 43804 43818 43911 44243 44262 44284 44398 45334 45364 45564 45668 45865 46247 46297 46306 46640 46925 46967 47137 47258 47589 47740 48105 48545 48652 48705https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/449/723?format=asciidefaultJ/A+A/449/723/starsStar positions and magnitudes (from Simbad)m_HD[AB] Multiplicity index on HDmeta.code.multipcharrecnoRecord number assigned by the VizieR team.
