cds-question@unistra.frmultiple-starssolar-system-planetsThe origin of Jupiter-mass planets with orbital periods of only a few days is still uncertain. It is widely believed that these planets formed near the water-ice line of the protoplanetary disk, and subsequently migrated into much smaller orbits. Most of the proposed migration mechanisms can be classified either as disk-driven migration, or as excitation of a very high eccentricity followed by tidal circularization. In the latter scenario, the giant planet that is destined to become a hot Jupiter spends billions of years on a highly eccentric orbit, with apastron near the water-ice line. Eventually, tidal dissipation at periastron shrinks and circularizes the orbit. If this is correct, then it should be especially rare for hot Jupiters to be accompanied by another giant planet interior to the water-ice line. Using the current sample of giant planets discovered with the Doppler technique, we find that hot Jupiters with P_orb_<10d are no more or less likely to have exterior Jupiter-mass companions than longer-period giant planets with P_orb_>=10d. This result holds for exterior companions both inside and outside of the approximate location of the water-ice line. These results are difficult to reconcile with the high-eccentricity migration scenario for hot Jupiter formation.2016ApJ...825...62Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/825/62CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)J/ApJ/821/89 : 12yrs of RV obs. of exoplanet systems (Bryan+, 2016)J/A+A/587/A64 : Physical properties of giant exoplanets (Santerne+, 2016)J/PASP/123/412 : Exoplanet Orbit Database (Wright+, 2011)J/ApJ/709/168 : Eccentric orbits in exoplanets (Anglada-Escude+, 2010)J/ApJ/697/544 : Planets orbiting metal-poor dwarfs.
