cds-question@unistra.frlate-type-starssolar-system-planetsradial-velocityA 10.24-day Neptune-mass planet was recently announced as orbiting the nearby M2 dwarf Gl 176, based on 28 radial velocities measured with the HRS spectrograph on the Hobby-Heberly Telescope. We obtained 57 radial velocities of Gl 176 with the ESO 3.6m telescope and the HARPS spectrograph, which is known for its sub-m/s stability. The median photon-noise standard error of our measurements is 1.1m/s, and the 4-year period over which they were obtained overlaps considerably with the epochs of the HET measurements. The HARPS measurements show no evidence of a signal at the period of the putative HET planet, suggesting that its detection was spurious. We do find, on the other hand, strong evidence of a lower mass 8.4M_Earth_ planet, in a quasi-circular orbit and at the different period of 8.78 days.2009A&A...493..645Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/493/645CatalogResearchIsServedByTAP 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/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/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/527/A63 : 7 new HARPS planetary systems radial velocities (Moutou+ 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/493/645https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/493/645http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/493/645https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/493/645https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/493/645http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/493/645GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/493/645/table2Radial-velocity measurements and error bars for Gl 176recnoRecord number assigned by the VizieR team.
