cds-question@unistra.frsolar-system-planetsradial-velocityWe report the detection of three new extrasolar planets orbiting the solar type stars HD 85390, HD 90156 and HD 103197 with the HARPS spectrograph mounted on the ESO 3.6-m telescope at La Silla observatory. HD 85390 has a planetary companion with a projected intermediate mass (42.0M_earth_) on a 788-day orbit (a=1.52AU) with an eccentricity of 0.41, for which there is no analogue in the solar system. A drift in the data indicates the presence of another companion on a long period orbit, which is however not covered by our measurements. HD 90156 is orbited by a warm Neptune analogue with a minimum mass of 17.98M_earth_ (1.05M_neptune_), a period of 49.8 days (a=0.25AU) and an eccentricity of 0.31. HD 103197 has an intermediate mass planet on a circular orbit (P=47.8d, Msini=31.2M_earth_). We discuss the formation of planets of intermediate mass (30-100M_earth_) which should be rare inside a few AU according to core accretion formation models.2011A&A...526A.111Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/526/A111CatalogResearchIsServedByTAP 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/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/A48 : HD125612, HD215497, HIP5158 HARPS RV curves (Lo Curto+, 2010)J/A+A/526/A112 : Radial velocities of HARPS metal-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/526/A111https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/526/A111http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/526/A111https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/526/A111https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/526/A111http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/526/A111GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/526/A111/table1HARPS radial velocity measurements of HD 85390JDJulian Datedtime.epochdoublerecnoRecord number assigned by the VizieR team.
