cds-question@unistra.frsolar-system-planetsradial-velocitymetallicityIn this paper we search for distant massive companions to known transiting gas giant planets that may have influenced the dynamical evolution of these systems. We present new radial velocity observations for a sample of 51 planets obtained using the Keck HIRES instrument, and find statistically significant accelerations in fifteen systems. Six of these systems have no previously reported accelerations in the published literature: HAT-P-10, HAT-P-22, HAT-P-29, HAT-P-32, WASP-10, and XO-2. We combine our radial velocity fits with Keck NIRC2 adaptive optics (AO) imaging data to place constraints on the allowed masses and orbital periods of the companions responsible for the detected accelerations. The estimated masses of the companions range between 1-500 M_Jup_, with orbital semi-major axes typically between 1-75 AU. A significant majority of the companions detected by our survey are constrained to have minimum masses comparable to or larger than those of the transiting planets in these systems, making them candidates for influencing the orbital evolution of the inner gas giant. We estimate a total occurrence rate of 51%+/-10% for companions with masses between 1-13 M_Jup_ and orbital semi-major axes between 1-20 AU in our sample. We find no statistically significant difference between the frequency of companions to transiting planets with misaligned or eccentric orbits and those with well-aligned, circular orbits. We combine our expanded sample of radial velocity measurements with constraints from transit and secondary eclipse observations to provide improved measurements of the physical and orbital characteristics of all of the planets included in our survey.2014ApJ...785..126Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/785/126CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/185 : Search for Jupiter-Mass Companions (Walker+, 1995)III/211 : Keck/HIRES Sky Line Atlas (Osterbrock+ 1997)J/ApJS/152/261 : Chromospheric Ca II emission in nearby stars (Wright+, 2004)J/MNRAS/426/739 : Velocities for seven transiting hot Jupiters (Hellier+, 2012)J/A+A/563/A22 : Radial velocities of 3 new hot Jupiters (Moutou+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/785/126https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/785/126http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/785/126https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/785/126https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/785/126http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/785/126GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/785/126/table1 (Stellar Parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/785/126/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/785/126/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/785/126/table1?GETtext/xml+votable180.050000true175.54622526.70656940.0055555555555555566/876 1275 2532 2551 2711 3344 6017 6181 6349 6539 6638 7036 7208 8197 8825 9173 9459 9482 9524 9811 10654 12424 12862 13143 13439 13569 13680 14825 14886 15129 15143 16432 20339 22001 22505 24409 25132 26062 28548 31641 32564 32749 35210 36142 38452 42936 43847 44648 46437 47476https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/785/126?format=asciiOpticaldefaultJ/ApJ/785/126/table3HIRES Radial Velocity MeasurementsrecnoRecord number assigned by the VizieR team.
