cds-question@unistra.frradial-velocitymultiple-starsWe report the detection of two new long-period giant planets orbiting the stars HD 95872 and HD 162004 ({psi}^1^ Dra B) by the McDonald Observatory planet search. The planet HD 95872b has a minimum mass of 4.6M_Jup_ and an orbital semimajor axis of 5.2AU. The giant planet {psi}^1^ Dra Bb has a minimum mass of 1.5M_Jup_ and an orbital semimajor axis of 4.4AU. Both of these planets qualify as Jupiter analogs. These results are based on over one and a half decades of precise radial velocity (RV) measurements collected by our program using the McDonald Observatory Tull Coude spectrograph at the 2.7m Harlan J. Smith Telescope. In the case of {psi}^1^ Dra B we also detect a long-term nonlinear trend in our data that indicates the presence of an additional giant planet, similar to the Jupiter-Saturn pair. The primary of the binary star system, {psi}^1^ Dra A, exhibits a very large amplitude RV variation due to another stellar companion. We detect this additional member using speckle imaging. We also report two cases --HD 10086 and HD 102870 ({beta} Virginis)-- of significant RV variation consistent with the presence of a planet, but that are probably caused by stellar activity, rather than reflexive Keplerian motion. These two cases stress the importance of monitoring the magnetic activity level of a target star, as long-term activity cycles can mimic the presence of a Jupiter-analog planet.2016ApJ...818...34Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/818/34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/576/A48 : Radial velocity monitoring for 6 stars (Moutou+, 2015)J/ApJ/804/146 : Atmospheric parameters for nearby B-F stars (David+, 2015)J/ApJS/210/5 : The twenty-five year Lick planet search (Fischer+, 2014)J/A+A/552/A6 : F-G main-sequence star abundances (Gonzalez Hernandez+, 2013)J/ApJ/764/78 : Oxygen abundances in nearby FGK stars (Ramirez+, 2013)J/A+A/546/A61 : Radial velocities for XHIP catalogue (de Bruijne+, 2012)J/ApJ/746/101 : Diameters and temperatures of AFG stars (Boyajian+, 2012)J/ApJ/732/55 : Abundances of stars with planets (Schuler+, 2011)J/AJ/141/45 : Speckel observations of HIP stars (Horch+, 2011)J/A+A/512/A54 : Teff and Fbol from Infrared Flux Method (Casagrande+, 2010)J/A+A/508/L17 : Abundances in solar analogs (Ramirez+, 2009)J/MNRAS/389/869 : Multiplicity among bright stellar systems (Eggleton+, 2008)J/A+A/465/271 : Oxygen abundances in nearby stars (Ramirez+, 2007)J/MNRAS/371/1140 : Radial velocities of K0 stars (Griffin+, 2006)J/ApJS/162/207 : Radial velocities of solar-type stars (Abt+, 2006)J/ApJS/161/444 : [Fe/H] & Teff for luminosity class IV-V stars (Taylor+, 2005)J/MNRAS/360/1345 : F- and G-type stars in solar neighbourhood (Karatas+, 2005)J/MNRAS/349/757 : Masses, ages and metallicities of F-G dwarfs (Lambert+, 2004)J/A+A/423/517 : Galactic disk late-type stars velocities (Rocha-Pinto+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/818/34https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/818/34http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/818/34https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/818/34https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/818/34http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/818/34GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/818/34/table1 (Stellar properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/818/34/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/818/34/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/818/34/table1?GETtext/xml+votable180.050000true165.8669625-22.09400280.0055555555555555566/2491 11732 25135 269753.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/818/34?format=asciiOpticaldefaultJ/ApJ/818/34/table4Differential radial velocity measurements for {psi}^1^ Draconis ArecnoRecord number assigned by the VizieR team.
