cds-question@unistra.frmultiple-starsradial-velocitysolar-system-planetsWe present the discovery of three modestly irradiated, roughly Neptune-mass planets orbiting three nearby Solar-type stars. HD42618b has a minimum mass of 15.4+/-2.4 M_{Earth}_, a semimajor axis of 0.55au, an equilibrium temperature of 337K, and is the first planet discovered to orbit the solar analogue host star, HD42618. We also discover new planets orbiting the known exoplanet host stars HD164922 and HD143761 ({rho} CrB). The new planet orbiting HD164922 has a minimum mass of 12.9+/-1.6 M_{Earth}_ and orbits interior to the previously known Jovian mass planet orbiting at 2.1au. HD164922c has a semimajor axis of 0.34au and an equilibrium temperature of 418K. HD143761c orbits with a semimajor axis of 0.44au, has a minimum mass of 25+/-2 M_{Earth}_, and is the warmest of the three new planets with an equilibrium temperature of 445K. It orbits exterior to the previously known warm Jupiter in the system. A transit search using space-based CoRoT data and ground-based photometry from the Automated Photometric Telescopes (APTs) at Fairborn Observatory failed to detect any transits, but the precise, high-cadence APT photometry helped to disentangle planetary-reflex motion from stellar activity. These planets were discovered as part of an ongoing radial velocity survey of bright, nearby, chromospherically inactive stars using the Automated Planet Finder (APF) telescope at Lick Observatory. The high-cadence APF data combined with nearly two decades of radial velocity data from Keck Observatory and gives unprecedented sensitivity to both short-period low-mass, and long-period intermediate-mass planets.2016ApJ...830...46Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/830/46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/805/175 : Keck and APF radial velocities of HD7924 (Fulton+, 2015)J/ApJS/210/5 : The twenty-five year Lick planet search (Fischer+, 2014)J/ApJ/772/80 : Radial velocities of HAT-P-17 (Fulton+, 2013)J/ApJ/770/69 : Kepler planet candidates radii (Petigura+, 2013)J/MNRAS/420/L23 : Non-resonant Kepler planetary systems (Veras+, 2012)J/ApJ/756/46 : Lithium abundances in HIP stars (Ramirez+, 2012)J/ApJ/745/24 : A search for new companions with CHARA (Raghavan+, 2012)J/ApJ/733/68 : Exoplanet masses derived from RVs (Brown+, 2011)J/AJ/142/19 : Speckle observations of KOI (Howell+, 2011)J/AJ/141/45 : Speckel observations of HIP stars (Horch+, 2011)J/ApJ/725/875 : Chromospheric activity for CPS stars (Isaacson+, 2010)J/other/Sci/330.653 : Detected planets in the Eta-Earth Survey (Howard+, 2010)J/ApJ/720/1290 : Abundances of stars hosting planets (Ghezzi+, 2010)J/AJ/138/312 : Activity of bright solar analogs (Hall+, 2009)J/ApJ/694/1085 : Radii of exoplanet host stars (van Belle+, 2009)J/ApJ/680/728 : Diameters of exoplanet host stars (Baines+, 2008)J/ApJ/649/1010 : Habitability of known exoplanetary systems (Jones+, 2006)J/ApJ/646/505 : Catalog of nearby exoplanets (Butler+, 2006)J/ApJ/457/L99 : 25yr CaII-HK obs. of F-K nearby stars (Baliunas+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/830/46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/830/46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/830/46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/830/46https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/830/46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/830/46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/830/46/table2 (Adopted stellar properties and orbital periods)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/830/46/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/830/46/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/830/46/table2?GETtext/xml+votable180.050000true93.00236176.78307140.0055555555555555566/9403 23583 325611.1166583743361574e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/830/46?format=asciidefaultJ/ApJ/830/46/table1Radial velocities of the three nearby solar-type starsrecnoRecord number assigned by the VizieR team.
