The frequency of JL planets in NYMGs appears to be higher than that obtained from radial velocity (RV) surveys. We extended the search for companions to three nearby clusters of intermediate age: Hyades, Coma Berenices, and Ursa Major. They are older and formed in more massive events than the NYMGs. The sample of host stars is complete for the core of the clusters, while we considered only a fraction of the tidal tails. We used the same methods considered for the members of NYMGs. We obtained a fairly complete sample of stellar companions and detected six massive JL planets. We found a lower frequency of equal-mass companions than in the NYMGs; this might be related to how binaries form in these environments. We also observed a concentration of stellar binaries in the cores of Ursa Major and Coma Berenices; we attribute this to the selective loss of low-mass systems. The observed scarcity of wide companions in Hyades can be due to the destruction of binaries in close encounters. The frequency of JL planets is lower than in the NYMGs but similar to that obtained from RV surveys. This extends the correlation with age and mass previously found for NYMGs. Results of this study alone do not indicate whether age or mass are the factors driving the observed correlation. A comparison of the frequencies of free-floating planets from microlenses and in young associations favours mass as the main driving parameter. Once the initial cluster mass function is considered, the frequency of JL planets in NYMGs is consistent with the results obtained using RVs.</description><source format="bibcode">2025A&amp;A...694A.175G</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/694/A175</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/694/A175</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/694/A175</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/694/A175</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/694/A175</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/694/A175</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/694/A175</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/A+A/694/A175/tablec1 (Photometry of stars)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/694/A175/tablec1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/694/A175/tablec1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/694/A175/tablec1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>158.7904</ra><dec>57.0826</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>5/84 87 5883-5884 5886 7120-7121 6/60 78 272 309 311 320 322-323 325 333-334 340-342 353 357 373 383 456 472 483 712 770 890 917 1024 1032-1033 1035 1042 1045 1058 1060 1064 1075 1211 1397 3383 4038 4920 5154 5235 5311 5631 6073 6082 6098 6217 6385 7763 8041 8496 8687 8717 9131 9281 9961 9969 9974 9979 9982-9983 10167 10276 10290 10334 10403 10426 10429 10477 10560 10653 10743 10748 10787 11079 11090 11094 11096-11097 11099 11109 11120 11126 11128 11145 11163 11165 11193 11197 11202 11204-11205 11225 11323 11333 11343 11348 11367 11374 11412 11417 11419 11421 11424 11426 11430 11449 11451 11462 11469-11470 11476 11482 11491 11496 11500 11502 11510 11691 11848 11872 14005 14902 15144 15177 16289 16903 17085 17486 17907 18210 19027 19867 20940 21060 23017 23329 23339 23342 23344 23383 23392 23396 23405 23410 23416 23423 23444 23450 23454 23463 23479 23489-23490 23493 23496-23497 23501-23504 23511 23513-23515 23518-23519 23523 23525-23527 23529 23541-23542 23548 23550 23774 24075 24099 24104 24110 24151 24192 24194-24195 24201-24203 24206-24207 24209 24223 24242 24248 24315 24842 25182 26302 26330 26779 27909 27930 27996 28022 28092-28094 28108 28116 28123 28128 28131 28137 28151 28154 28272 28397 28416 28433 28439 28442 28446-28447 28469 28489-28490 28494 28515 28537 28560 28567 28696 31929 32058 34217 34520 39994 40408 41272 48188</spatial><spectral>1.9867573869263685e-19 3.916500758235022e-19</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/694/A175?format=ascii</footprint><waveband>Optical</waveband><waveband>Infrared</waveband></coverage><tableset><schema><name>default</name><table><name>J/A+A/694/A175/tablec1</name><description>Photometry of stars</description><column><name>recno</name><description>Record number assigned by the VizieR team.
