The addition of more Kepler and Transiting Exoplanet Survey Satellite (TESS) systems in 2022 filled this region of the diagram of stellar rotation period (Prot) versus the planet orbital period (Porb). We revisited the Prot extraction of Kepler planet-host stars, we classify the stars by their spectral type, and we studied their Prot-Porb relations. We only used confirmed exoplanet systems to minimize biases. In order to learn about the physical processes at work, we used the star-planet evolution code ESPEM (French acronym for Evolution of Planetary Systems and Magnetism) to compute a realistic population synthesis of exoplanet systems and compared them with observations. Because ESPEM works with a single planet orbiting around a single main-sequence star, we limit our study to this population of Kepler observed systems filtering out binaries, evolved stars, and multi-planets. We find in both, observations and simulations, the existence of a dearth in close-in planets orbiting around fast-rotating stars, with a dependence on the stellar spectral type (F, G, and K), which is a proxy of the mass in our sample of stars. There is a change in the edge of the dearth as a function of the spectral type (and mass). It moves towards shorter Prot as temperature (and mass) increases, making the dearth look smaller. Realistic formation hypotheses included in the model and the proper treatment of tidal and magnetic migration are enough to qualitatively explain the dearth of hot planets around fast-rotating stars and the uncovered trend with spectral type.2023A&A...679L..12Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/679/L12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/133 : Kepler Input Catalog (Kepler Mission Team, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/679/L12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/679/L12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/679/L12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/679/L12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/679/L12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/679/L12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/679/L12/table1 (Stellar and exoplanet properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/679/L12/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/679/L12/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/679/L12/table1?GETtext/xml+votable180.050000true291.137577236.5773550.0055555555555555564/933-935 946 5/3645-3647 3689 3691 3693-3695 3704 3706 3730 3776-3778 3780 3782-3783 3789 3792-3793 6/14567 14573 14578-14579 14731 14734-14735 14744 14746 14750-14752 14754-14755 14760 14762-14763 14768 14770-14771 14792 14794-14795 14828 14830 14914-14915 14917-14919 14924-14925 14927 15040-15041 15043-15045 15057 15060-15061 15116 15118-15119 15124 15126-15127 15153-15155 15160 15178 15200https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/679/L12?format=asciiOpticaldefaultJ/A+A/679/L12/table1Stellar and exoplanet propertiesSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
