cds-question@unistra.frsolar-system-planetsradial-velocityWe report the detection of a planetary system around BD-08 2823, that includes at least one Uranus-mass planet and one Saturnmass planet. This discovery serendipitously originates from a search for planetary transits in the Hipparcos photometry database. This program preferentially selected active stars and did not allow the detection of new transiting planets. It allowed however the identification of the K3V star BD-08 2823 as a target harboring a multiplanet system, that we secured and characterized thanks to an intensive monitoring with the HARPS spectrograph at the 3.6-m ESO telescope in La Silla. The stellar activity level of BD-08 2823 complicates the analysis but does not prohibit the detection of two planets around this star. BD-08 2823b has a minimum mass of 14.4+/-2.1M_{earth}_ and an orbital period of 5.60days, whereas BD-08 2823c has a minimum mass of 0.33+/-0.03M_{Jup}_ and an orbital period of 237.6days. This new system strengthens the fact that low-mass planets are preferentially found in multiplanetary systems, but not around high-metallicity stars as this is the case for massive planets. It also supports the belief that active stars should not be neglected in exoplanet searches, even when searching for low-mass planets.2010A&A...512A..46Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/512/A46CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/469/L43 : Radial velocities of Gl 581 (Udry+, 2007)J/A+A/474/293 : Radial velocities of GJ 674 (Bonfils+, 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 : RV of 6 stars with long-period giant planets (Moutou+, 2009)J/A+A/496/521 : Radial velocities of HD45364 (Correia+, 2009)J/A+A/496/527 : Radial velocity curves of HD 47186 & HD 181433 (Bouchy+, 2009)J/A+A/507/487 : GJ 581 radial velocity curve (Mayor+, 2009)J/A+A/512/A47 : Radial velocites 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/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/526/A141 : HIP 85647 & Gl 676A radial velocities (Forveille+, 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/512/A46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/512/A46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/512/A46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/512/A46https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/512/A46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/512/A46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/512/A46/table1HARPS measurements of BD-08 2823recnoRecord number assigned by the VizieR team.
