cds-question@unistra.frsurveysmultiple-starsexoplanetsradial-velocityOne of the main scientific drivers for ESPRESSO, Echelle SPectrograph, is the detection and characterization of Earth-class exoplanets. With this goal in mind, the ESPRESSO guaranteed time observations (GTO) Catalog identifies the best target stars for a blind search for the radial velocity (RV) signals caused by Earth-class exoplanets. Using the most complete stellar catalogs available, we screened for the most suitable G, K, and M dwarf stars for the detection of Earth-class exoplanets with ESPRESSO. For most of the stars, we then gathered high-resolution spectra from new observations or from archival data. We used these spectra to spectroscopically investigate the existence of any stellar binaries, both bound or background stars. We derived the activity level using chromospheric activity indexes using log (R'_HK_), as well as the projected rotational velocity vsini. For the cases where planet companions are already known, we also looked at the possibility that additional planets may exist in the host's habitable zone using dynamical arguments. We estimated the spectroscopic contamination level, vsini, activity, stellar parameters and chemical abundances for 249 of the most promising targets. Using these data, we selected 45 stars that match our criteria for detectability of a planet like Earth. The stars presented and discussed in this paper constitute the ESPRESSO GTO catalog for the RV blind search for Earth-class planets. They can also be used for any other work requiring a detailed spectroscopic characterization of stars in the solar neighborhood.2019A&A...629A..80Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/629/A80CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/629/A80https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/629/A80http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/629/A80https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/629/A80https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/629/A80http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/629/A80GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/629/A80/tableb12 (Derived parameters (tabel B1) and stellar parameters (table B2) for the first stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/629/A80/tableb12?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/629/A80/tableb12?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/629/A80/tableb12?GETtext/xml+votable180.050000true1.350417-37.3570280.005555555555555556Cone search capability for table J/A+A/629/A80/table6 (Forty-five best final targets for RV observation)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/629/A80/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/629/A80/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/629/A80/table6?GETtext/xml+votable180.050000true266.03625-51.8335830.0055555555555555566/93 95 101 137 400 497 610 766 841 1033 4158 4250 4444 4708 5009 6183 6219 8627 8689 12464 12612 12646 12679 12956 12995 13451 14419 16391 16667 16763 16827 17023 17028 17042 17084 17425 17656 18104 18139 18466 18496 18619 18710 18802 19064 19466 19799 20023 20100 20145 20178 20217 20886 20896 20973 21136 21149 21177 21233 21572 22040 22148 22277 22289 22293 22309 22709 22813 22818 22841 22969 23057 23076 23096 23190 23363 23369 23564 23643 23695 23705 23731 23735 23940 24212 24713 24810 24921 24924 25176 25279 25407 25820 25863 26172 26216 26538 26560 26583 27040 27132 27179 27201 27220 27392 27402 27459 27993 28341 28935 28955 29131 29196 29280 29585 29684 29851 30100 30170 30339 30429 30505 30518 30638 30665 30748 30771 30965 31082 31101 31191 31253 31303 31478 31581 31619 31781 31998 32017 32296 32335 33221 33552 33849 34181 34288 34345 34446 34817 34823 35079 35301 35759 36483 36502 36614 36664 36693 36697 36788 36945 37041 37408 37595 37654 37828 38238 38247 38359 38430 38486 38490 38973 39093 39200 39284 39302 39305 39441 39709 40078 40588 40688 40692 40811 41469 41981 42101 42198 42248 42290 42314 42512 42524 42592 42652 42713 42845 42884 42956 43032 43840 43851 43889 44125 44277 44382 44728 44789 44860 44883 44936-44937 44967 45113 45269 45419 45564 45669 46112 46247 46632 46640 46718 46925 47165 47352 47414 47589 47997 48087 48263 48274 48652 48852 48906 48943 48985 49060https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/629/A80?format=asciidefaultJ/A+A/629/A80/tableb12Derived parameters (tabel B1) and stellar parameters (table B2) for the first stars[Fe/H]?
