cds-question@unistra.frsolar-system-planetsradial-velocityWe report the discovery of a planetary system around HD 9446, performed from radial velocity measurements secured with the spectrograph SOPHIE at the 193-cm telescope of the Haute-Provence Observatory for more than two years. At least two planets orbit this G5V, active star: HD 9446b has a minimum mass of 0.7M_Jup_ and a slightly eccentric orbit with a period of 30-days, whereas HD 9446c has a minimum mass of 1.8M_Jup_ and a circular orbit with a period of 193-days. As for most of the known multiple planet systems, the HD 9446-system presents a hierarchical disposition with a massive outer planet and a lighter inner planet.2010A&A...513A..69Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/513/A69CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/410/1039 : Northern extra-solar planets ELODIE survey I (Perrier+, 2003)J/A+A/410/1051 : Northern extra-solar planets ELODIE survey II (Naef+, 2003)J/A+A/414/351 : Northern extra-solar planets ELODIE survey III (Naef+, 2004)J/A+A/479/271 : Northern extra-solar planets ELODIE survey IV (Correia+, 2008)J/A+A/505/853 : HD 16760 radial velocity curve (Bouchy+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/513/A69https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/513/A69http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/513/A69https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/513/A69https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/513/A69http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/513/A69GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/513/A69/table1Radial velocities of HD 9446 measured with SOPHIErecnoRecord number assigned by the VizieR team.
