cds-question@unistra.frmultiple-starssolar-system-planetsorbitsThe two dominant features in the distribution of orbital parameters for close-in exoplanets are the prevalence of circular orbits for very short periods, and the observation that planets on closer orbits tend to be heavier. The first feature is interpreted as a signature of tidal evolution, while the origin of the second, a 'mass-period relation' for hot Jupiters, is not understood. In this paper we reconsider the ensemble properties of transiting exoplanets with well-measured parameters, focusing on orbital eccentricity and the mass-period relation. We recalculate the constraints on eccentricity in a homogeneous way, using new radial velocity data, with particular attention to statistical biases. We find that planets on circular orbits gather in a well-defined region of the mass-period plane, close to the minimum period for any given mass. Exceptions to this pattern reported in the literature can be attributed to statistical biases. The ensemble data is compatible with classical tide theory with orbital circularization caused by tides raised on the planet, and suggest that tidal circularization and the stopping mechanisms for close-in planets are closely related to each other. The position mass-period relation is compatible with a relation between a planet's Hill radius and its present orbit.2011MNRAS.414.1278Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/414/1278CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.inscience.ch/transits : Parameters for transiting exoplanetshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/414/1278https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/414/1278http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/414/1278https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/414/1278https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/414/1278http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/414/1278GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/414/1278/table1 (*Eccentricity of transiting planets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/414/1278/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/414/1278/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/414/1278/table1?GETtext/xml+votable180.050000true102.079875-3.10213890.0055555555555555566/876 1275 2711 3344 3876 4990 6381 6539 6638 7036 7208 7240 8825 9173 9355 9459 9524 9811 10654 10730 12424 12644 12983 13439 13569 13680 13702 14772 14825-14826 14886 14914 14936 15040 15129 15143 15149 16947 17172 20116 20339 22065 22120 22208 24409 28548 30293 30295 30450-30451 30466 31216 32727 32749 35210 36142 38452 42936 43847 44648 46421 46437 47476https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/414/1278?format=asciidefaultJ/MNRAS/414/1278/table1*Eccentricity of transiting planetsrecnoRecord number assigned by the VizieR team.
