cds-question@unistra.frmultiple-starssolar-system-planetsradial-velocityWe present observations of the Rossiter-McLaughlin effect for two exoplanetary systems, revealing the orientations of their orbits relative to the rotation axes of their parent stars. HAT-P-4b is prograde, with a sky-projected spin-orbit angle of {lambda}=-4.9+/-11.9{deg}. In contrast, HAT-P-14b is retrograde, with {lambda}=189.1+/-5.1{deg}. These results conform with a previously noted pattern among the stellar hosts of close-in giant planets: hotter stars have a wide range of obliquities and cooler stars have low obliquities. This, in turn, suggests that three-body dynamics and tidal dissipation are responsible for the short-period orbits of many exoplanets. In addition, our data revealed a third body in the HAT-P-4 system, which could be a second planet or a companion star.2011AJ....141...63Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/141/63CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/527/A85 : Light curves of HAT-P-3b and HAT-P-14b (Nascimbeni+, 2011)J/ApJ/715/458 : Differential photometry of HAT-P-14 (Torres+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/141/63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/141/63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/141/63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/141/63https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/141/63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/141/63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/141/63/table1Relative radial velocity measurements of HAT-P-14 (P=4.6276690+/-0.0000050)recnoRecord number assigned by the VizieR team.
