cds-question@unistra.frmultiple-starsorbitsWe assess the importance of tidal evolution and its interplay with magnetic braking in the population of hot-Jupiter planetary systems. By minimizing the total mechanical energy of a given system under the constraint of stellar angular momentum loss, we rigorously find the conditions for the existence of dynamical equilibrium states. We estimate their duration, in particular when the wind torque spinning down the star is almost compensated for by the tidal torque spinning it up. We introduce dimensionless variables to characterize the tidal evolution of observed hot Jupiter systems and discuss their spin and orbital states using generalized Darwin diagrams based on our new approach. We show that their orbital properties are related to the effective temperature of their host stars. The long-term evolution of planets orbiting F- and G-type stars is significantly different owing to the combined effect of magnetic braking and tidal dissipation. The existence of a quasi-stationary state, in the case of short-period planets, can significantly delay their tidal evolution that would otherwise bring the planet to fall into its host star. Most of the planets known to orbit F-type stars are presently found to be near this stationary state, probably in a configuration not too far from what they had when their host star settled on the zero-age main sequence. Considering the importance of angular momentum loss in the early stages of stellar evolution, our results indicate that it has to be considered to properly test the migration scenarios of planetary system formation.2015A&A...574A..39Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/574/A39CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/574/A39https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/574/A39http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/574/A39https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/574/A39https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/574/A39http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/574/A39GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/574/A39/table4 (Main stellar and planetary parameters of the systems considered in Sect. 4)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/574/A39/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/574/A39/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/574/A39/table4?GETtext/xml+votable180.050000true280.68729145.93768140.0055555555555555566/790 876 2551 2584 2596 2711 4990 6017 6181 6381 6539 8197 8237 9355 9459 9482 10654 10730 10953 12644 13044 13439 13569 13941 14772 14779 14816 14825-14826 14936 14961 14973 15029 15040 15112 15140 15143 15149 15160 15162 15218 15550 15950 16405 16947 17226 18093 18569 18943 20116 20186 21026 21254 21989 22034 22040 22078 22120 22169 22208 22505 22519 22816 24815 25132 25604 25885 25950 26019 26771 28400 28433 30009 30240 30444 30450-30451 30456 30466 30485 31541 31641 32749 33798 35210 35993 36142 36165 36667 37923 38452 38682 39487 39611 39673 40862 43625 43775 43960 44648 45051 45922 46421 46429 46437 48803https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/574/A39?format=asciidefaultJ/A+A/574/A39/table4Main stellar and planetary parameters of the systems considered in Sect. 4recnoRecord number assigned by the VizieR team.
