cds-question@unistra.frmultiple-starssolar-system-planetsradial-velocityIn 1992 we began a precision radial velocity (RV) survey for planets around solar-like stars with the Coude Echelle Spectrograph and the Long Camera (CES LC) at the 1.4m telescope in La Silla (Chile). We have continued the survey with the upgraded CES Very Long Camera (VLC) and HARPS, both at the 3.6m telescope, until 2007. The observations for 31 stars cover a time span of up to 15 years and the RV precision permit a search for Jupiter analogues. We perform a joint analysis for variability, trends, periodicities, and Keplerian orbits and compute detection limits. Moreover, the HARPS RVs are analysed for correlations with activity indicators (CaII H&K and CCF shape). We achieve a long-term RV precision of 15m/s (CES+LC, 1992-1998), 9m/s (CES+VLC, 1999-2006), and 2.8m/s (HARPS, 2003-2009, including archive data), resp. This enables us to confirm the known planets around Iota Hor, HR 506, and HR 3259. A steady RV trend for Eps Ind A can be explained by a planetary companion. On the other hand, we find previously reported trends to be smaller for Beta Hyi and not present for Alp Men. The candidate planet Eps Eri b was not detected despite our better precision. Also the planet announced for HR 4523 cannot be confirmed. Long-term trends in several of our stars are compatible with known stellar companions. We provide a spectroscopic orbital solution for the binary HR 2400 and refined solutions for the planets around HR 506 and Iota Hor. For some other stars the variations could be attributed to stellar activity.2013A&A...552A..78Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/552/A78CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/487/373 : Spectroscopic parameters of 451 HARPS-GTO stars (Sousa+, 2008)J/A+A/497/563 : Chemical abundances of 451 stars (Neves+, 2009)J/A+A/496/527 : Radial velocity curves of HD 47186 & HD 181433 (Bouchy+, 2009)J/A+A/505/859 : M dwarfs radial velocities (Zechmeister+, 2009)J/A+A/526/A99 : Metal-poor solar-type stars spectroscopy & masses (Sousa+ 2011)J/A+A/545/A32 : Chemical abundances of 1111 stars (Adibekyan+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/552/A78https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/552/A78http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/552/A78https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/552/A78https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/552/A78http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/552/A78GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/552/A78/stars (Studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/552/A78/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/552/A78/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/552/A78/stars?GETtext/xml+votable180.050000true5.017917-64.8747220.0055555555555555566/16903 17425 28987 33281 33552 33717 34817 34905 35064 35351 35948 36379 36693 36697 37408 38238 39096 39500 39953 40692 41763 42285 43639 44284 45564 45865 46247 46640 47589https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/552/A78?format=asciiOpticaldefaultJ/A+A/552/A78/starsStudied starsrecnoRecord number assigned by the VizieR team.
