cds-question@unistra.frlate-type-starsmetallicityspectroscopysolar-system-planetsMost of our current understanding of the planet formation mechanism is based on the planet metallicity correlation derived mostly from solar-type stars harbouring gas-giant planets. To achieve a more extensive grasp on the substellar formation process, we aim to analyse in terms of their metallicity a diverse sample of stars (in terms of mass and spectral type) covering the whole range of possible outcomes of the planet formation process (from planetesimals to brown dwarfs and low-mass binaries). Our methodology is based on the use of high-precision stellar parameters derived by our own group in previous works from high-resolution spectra by using the iron ionisation and equilibrium conditions. All values were derived in an homogeneous way, except for the M dwarfs where a methodology based on the use of pseudo equivalent widths of spectral features was used. Our results show that as the mass of the substellar companion increases the metallicity of the host star tends to lower values. The same trend is maintained when analysing stars with low-mass stellar companions and a tendency towards a wide range of host star's metallicity is found for systems with low-mass planets. We also confirm that more massive planets tend to orbit around more massive stars. The core-accretion formation mechanism for planet formation achieves its maximum efficiency for planets with masses in the range 0.2 and 2M_{Jup}_. Substellar objects with higher masses have higher probabilities of being formed as stars. Low-mass planets and planetesimals might be formed by core-accretion even around low-metallicity stars.2019A&A...624A..94Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/624/A94CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/624/A94https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/624/A94http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/624/A94https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/624/A94https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/624/A94http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/624/A94GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/624/A94/tablea1 (Basic properties of the stars analysed in this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/624/A94/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/624/A94/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/624/A94/tablea1?GETtext/xml+votable180.050000true0.543088127.08179920.0055555555555555566/137 341 377 679 684 706 748 824 1061 1275 1341 1452 1544 1875 2273 2305 2312 2366 2374 2416 2472 2490 2541 2652 2697 2822 2834 2837 2923 3020 3102 3118 3134 3932 3979 4136 4227 4285 4429 4441 4444 4766 4854 4867 4913 4942 5009 5074 5154 5304 5309 5413 5522 5815 5836 6006 6066 6078 6219 6308 6523 6568 6760 6766 6831 6926 6941 7208 7227 7390 7760 7763 8094 8109 8296 8357 8398 8440 8466 8476 8602 8700 8704 8756 8788 8843 8862 8995 9219 9350 9403 9459 9476 9662 9753 9801 9835 9843 9873 9893 10034 10225 10313 10327 10333-10334 10375 10812 11075 11087 11103 11126 11142 11163 11314 11352 11405 11473 11510 11620 11633 11699 11806 11834 12030 12056 12146 12232 12306 12477 12482 12526 12592 12612 12654 12720 12735 12856 12899 12944 12956 12995 13114 13138 13177 13230-13231 13414 13643 13667 13731 13734 13763 13778 14013 14084 14220 14275 14278 14387 14416 14419 14427 14434 14466 14516 14522 14539 14548 14604 14624 14762 14837 14896 15129 15170 15174 15227 15273 15345 15363 16035 16069 16391 16627 16678-16679 16689 16707 16883 16995 17171 17183 17266 17296 17299 17341 17391 17425 17486 17576 17607 17730-17731 17870 17881 17954 18028 18139 18416 18441 18466 18496 18614 18641 18666 18688 18778 18821 18835 18911 18953 19064 19156 19414 19466 19585 19874 19912 19985 20072 20100 20145 20206 20278 20328 20593 20701 20886 20896 21003 21060 21177 21185 21194 21484 21531 21703 21838 21953 22036 22040 22252 22309 22518 22590 22708 22807 22818 22868 22878 23013 23097 23190 23201 23230 23342 23511 23774 24019 24028 24151 24227 24330 24713 24729 24810 24831 24924 25009 25125 25140 25231 25401 25407 25593 25863 25939 25966 25989 26077 26120 26133 26183 26242 26287 26298 26462 26521 26560 26575 26583 26657 26706-26707 26972 26978 26997 27018 27060 27088 27164 27201 27220 27374 27392 27881 27973 27975 28041 28044 28093-28094 28122 28130 28400 28436 28539 28605 28763 28792 28865 28955 28987 29291 29513 29541 29589 29684 29815 30015 30064 30100 30170-30171 30278 30339 30398 30416 30419 30505 30518 30526 30529 30535 30541 30576 30668 30693 30770-30771 30833 30878 30890 30965 31130 31191 31193 31374 31380 31399 31416 31425 31433 31494 31720 31742 31751 31842 31860 32027 32192 32335 32619 32643 32725 32731 32749 32757 32848 32930 33456 33552 33630 33813 33923 34069 34181 34390 34446 34674 34817 34864 34905 34951 35064 35079 35362 35392 35497 35753 35954 36035 36115 36288 36365 36379 36506 36664 36693 36697 36723 36784 37379 37408 37461 37573 37585 37654 37955 38152 38238 38456 38545 38551 38765 38932 38936 39257 39280 39284 39500 39646 39709 39926 40078 40101 40143 40220 40242 40250 40400 40442 40515 40692 40892 40932 41143 41167 41446 41591 41607 41763 41912 42044 42054 42221 42248 42255 42290 42314 42333 42459 42510 42570 42652 42760 42769 42784 43012 43022 43187 43228 43595 43639 43677 43813 43911 43989 44243 44557 44669 44799 44921 45143 45168 45258 45265 45317 45322 45334 45364 45430 45485 45668-45669 45865 45927 45941 46112-46113 46247 46297 46306 46566 46632 46640 46681 46967 46982 47137 47212 47409 47550 47589-47590 47706 47740 47910 48105 48108-48109 48254 48274 48334 48402 48545 48652 48705 489233.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/624/A94?format=asciidefaultJ/A+A/624/A94/tablea1Basic properties of the stars analysed in this workSimbadNameSimbad column added by the CDSmeta.idcharHD?
