cds-question@unistra.frexoplanetsradial-velocityvisible-astronomyspectroscopyAnalysis of new precision radial velocity (RV) measurements from the Lick Automated Planet Finder and Keck HIRES has yielded the discovery of three new exoplanet candidates orbiting the nearby stars HD190007 and HD216520. We also report new velocities from the APF and the Planet Finder Spectrograph and updated orbital fits for the known exoplanet host stars GJ686 and HD180617. Of the newly discovered planets, HD 190007b has a period of P=11.72 days, an RV semiamplitude of K=5.64{+/-}0.55m/s, a minimum mass of Mpl=16.46{+/-}1.66M{Earth}, and orbits the slightly metal-rich, active K4V star HD 190007. For HD 216520b, we find P=35.45days, K=2.28{+/-}0.20m/s, and Mpl=10.26{+/-}0.99M{Earth}, while for HD216520c, P=154.43days, K=1.29{+/-} 0.22m/s, and Mpl=9.44{+/-}1.63M{Earth}. Both planets orbit the slightly metal-poor, inactive K0V star HD216520. Our updated best-fit models for HD180617b and GJ686b are in good agreement with the published results. For HD180617b, we obtain P=105.91days and Mpl=12.214{+/-}1.05M{Earth}. For GJ686b, we find P=15.53days and Mpl=6.624{+/-}0.432M{Earth}. Using an injection-recovery exercise, we find that HD190007b and HD216520b are unlikely to have additional planets with masses and orbital periods within a factor of 2, in marked contrast to ~85% of planets in this mass and period range discovered by Kepler.2021AJ....161...10Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/10CatalogResearchIsServedByTAP VizieR generic servicerelated-toIII/159 : Ca II H and K Measurements Made at MWO (Duncan+ 1991)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/335 : Revised catalog GALEX UV sources (GUVcat_AIS GR6+7) (Bianchi+ 2017)I/345 : Gaia DR2 (Gaia Collaboration, 2018)I/349 : StarHorse, Gaia DR2 photo-astrometric distances (Anders+, 2019)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)J/AJ/126/2048 : NStars project: the Northern Sample.
