cds-question@unistra.frsolar-system-planetsradial-velocityPrecise radial-velocity measurements with the HARPS spectrograph reveal the presence of two planets orbiting the solar-type star HD 45364. The companion masses are Msini=0.187M_{Jup} and 0.658M_{Jup}, with semi-major axes of a=0.681AU and 0.897AU, and eccentricities of e=0.168 and 0.097, respectively. A dynamical analysis of the system further shows a 3:2 mean motion resonance between the two planets, which prevents close encounters and ensures the stability of the system over 5Gyr. This is the first time that such a resonant configuration has been observed for extra-solar planets, although there is an analogue in our Solar System formed by Neptune and Pluto. This singular planetary system may provide important constraints on planetary formation and migration scenarios.2009A&A...496..521Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/496/521CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/474/293 : Radial velocities of GJ 674 (Bonfils+, 2007)J/A+A/469/L43 : Radial velocities of Gl 581 (Udry+, 2007)J/A+A/493/639 : Velocity curves of HD 40307 (Mayor+, 2009)J/A+A/493/645 : Gl 176 radial velocities (Forveille+, 2009)J/A+A/496/513 : Six stars with long-period giant planets RV (Moutou+, 2009)J/A+A/496/527 : Radial velocity of HD 47186 and HD 181433 (Bouchy+, 2009)J/A+A/507/487 : GJ 581 radial velocity curve (Mayor+, 2009)J/A+A/512/A46 : Radial velocities of BD-08 2823 (Hebrard+, 2010)J/A+A/512/A47 : Radial velocities of 3 stars with giant planets (Santos+ 2010)J/A+A/512/A48 : HD125612, HD215497, HIP5158 HARPS RV curves (Lo Curto+, 2010)J/A+A/523/A15 : RV data for the 8 targets (Naef+, 2010)J/A+A/526/A141 : HIP 85647 & Gl 676A radial velocities (Forveille+, 2011)J/A+A/526/A111 : HD 85390, 90156 and 103197 radial velocity (Mordasini+, 2011)J/A+A/526/A112 : Radial velocities of HARPS metail-poor sample (Santos+ 2011)J/A+A/527/A63 : 7 new HARPS planetary systems radial velocities (Moutou+ 2011)J/A+A/528/A112 : Radial velocities of HD 10180 (Lovis+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/496/521https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/496/521http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/496/521https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/496/521https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/496/521http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/496/521GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/496/521/hd45364Radial velocity taken with CORALIE spectrographrecnoRecord number assigned by the VizieR team.
