cds-question@unistra.frsurveysearly-type-starslate-type-starsradial-velocityThe search of close (a<~5au) giant planet (GP) companions with radial velocity (RV) around young stars and the estimate of their occurrence rates is important to constrain the migration timescales. Furthermore, this search will allow the giant planet occurrence rates to be computed at all separations via the combination with direct imaging techniques. The RV search around young stars is a challenge as they are generally faster rotators than older stars of similar spectral types and they exhibit signatures of magnetic activity (spots) or pulsation in their RV time series. Specific analyses are necessary to characterize, and possibly correct for, this activity. Our aim is to search for planets around young nearby stars and to estimate the GP occurrence rates for periods up to 1000 days. We used the SOPHIE spectrograph on the 1.93m telescope at the Haute-Provence Observatory to observe 63 A-M young (<400Myr) stars. We used our Spectroscopic data via Analysis of the Fourier Interspectrum Radial velocities (SAFIR) software to compute the RVs and other spectroscopic observables. We then combined this survey with the HARPS YNS survey to compute the companion occurrence rates on a total of 120 young A-M stars. Results. We report one new trend compatible with a planetary companion on HD 109647. We also report HD 105693 and HD 112097 as binaries, and we confirm the binarity of HD 2454, HD13531, HD 17250 A, HD 28945, HD 39587, HD 131156, HD 142229, HD 186704 A, and HD 195943. We constrained for the first time the orbital parameters of HD 195943 B. We refute the HD 13507 single brown dwarf (BD) companion solution and propose a double BD companion solution. Two GPs were previously reported from this survey in the HD 113337 system. Based on our sample of 120 young stars, we obtain a GP occurrence rate of 1^+2/2^_0/3_% for periods lower than 1000 days, and we obtain an upper limit on BD occurrence rate of 0.9^+2^_0.9_% in the same period range. We report a possible lack of close (P {in} [1; 1000] days) GPs around young FK stars compared to their older counterparts, with a confidence level of 90%.2021A&A...650A..39Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/650/A39CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/633/A44 : HARPS Young Nearby Stars - YNS (Grandjean+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/650/A39https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/650/A39http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/650/A39https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/650/A39https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/650/A39http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/650/A39GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/650/A39/tablea1 (Stellar characteristics of the SOPHIE YNS survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/650/A39/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/650/A39/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/650/A39/tablea1?GETtext/xml+votable180.050000true2.1072733336.6168022220.005555555555555556Cone search capability for table J/A+A/650/A39/tablea3 (Stellar characteristics of the HARPS YNS survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/650/A39/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/650/A39/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/650/A39/tablea3?GETtext/xml+votable180.050000true1.468937222-41.7530683330.0055555555555555566/46 940 2366 3383 4190 4438 4444 5088 6217 6670 8357 8790 10238 11145 11165 11176 11547 11910 12478 12592 13802 14252 16220 16393 16543 16853 16930 17274 17288 17541 17552 17607 17752 18210 18802 19509 19547 20125 21748 21953 22146 22773 23137 23140 23155 23230 23342 23731 23774 23895 24117 24151 24221 24239 24633 25015 25199 25793 26521 27374 27392 27395 27462 27884 27909 28041 28197 28341 28737 30419 30484 30539 31104 31399 31449 32147 32617 33312 33598 33850 34054 34074 34245 34342 34436 34683 34825 34829 35497 36664 36713 37175 37419 37616 38151 38765 38936 38950 39044 39693 39735 40717 40784 40811 42072 42147 42601 42910 43130 43150 43555 44088 45247 45538 45621 45746 45927 46383 46566 46923 46939 47101 47205 47287 47299 47598 47626 47910 48163 48274 48627 48651https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/650/A39?format=asciidefaultJ/A+A/650/A39/tablea1Stellar characteristics of the SOPHIE YNS surveyIR[yn-] IR excess flag (G2)meta.codecharSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
