Here, we present the radial velocity measurements for 378 N2K target stars that were observed with the HIRES spectrograph at Keck Observatory between 2004 and 2017. With this data set, we announce the discovery of six new gas giant exoplanets: a double-planet system orbiting HD 148164 (Msini of 1.23 and 5.16 M_JUP_) and single planet detections around HD 55696 (Msini=3.87 M_JUP_), HD 98736 (Msini=2.33 M_JUP_), HD 203473 (Msini=7.8 M_JUP_), and HD 211810 (Msini=0.67 M_JUP_). These gas giant companions have orbital semimajor axes between 1.0 and 6.2 au and eccentricities ranging from 0.13 to 0.71. We also report evidence for three gravitationally bound companions with Msini between 20 and 30 M_JUP_, placing them in the mass range of brown dwarfs, around HD 148284, HD 214823, and HD 217850, and four low-mass stellar companions orbiting HD 3404, HD 24505, HD 98630, and HD 103459. In addition, we present updated orbital parameters for 42 previously announced planets. We also report a nondetection of the putative companion HD 73256 b. Finally, we highlight the most promising candidates for direct imaging and astrometric detection, and we find that many hot Jupiters from our sample could be detectable by state-of-the-art telescopes such as Gaia.2018AJ....156..213Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/213CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)V/136 : Teff and metallicities for Tycho-2 stars (Ammons+, 2006)J/ApJ/637/1102 : Lick indices for metal-rich stars (Robinson+, 2006)J/ApJS/169/430 : Atmospheric parameters of 1907 metal-rich starshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/156/213https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/156/213http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/156/213https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/156/213https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/156/213http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/156/213GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/156/213/table3 (Properties of N2K stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/156/213/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/156/213/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/156/213/table3?GETtext/xml+votable180.050000true344.445184738.67509860.0055555555555555566/0 31 48 75 86 220 276 336 418 431 521 716 892 1042 1058 1151 1184 1288 1318 1492 1508 1852 2068 2153 2274 2374 2568 2816 3085 3147 3268 3433 3572 3575 3645 3876 4102 4285 4321 4377 4429 4611 4681 4758 4835 4867 4881 4917 4932 4993 5067 5143 5339 5447 5524 5553 5843 5973 6007 6078 6142 6293 6341 6539 6718 6737 6790 6821 6971 7171 7352 7416 7546 7721 7741 7933 8319 8580 8618 9077 9173 9301 9365 9391 9435 9459 9591 9654 9776 9811 9885 10031 10079 10140 10207 10238 10301 10552 10654 10730 10766 10787 10796 10859 10894 11014 11059 11091 11146 11194 11309 11916 11994 12203 12352 12418 12490 12540 12556 12579 12649 12761 12857 12939 12940 12976 13101 13287 13423 13425 13515 13563 13650 13661 13702 13900 13959 14079 14110 14129 14155 14305 14901 14947 15319 15617 15618 15642 15691 15856 16577 16592 16627 16632 16678 16776 17011 17035 17098 17338 17339 17447 17718 17768 17888 17906 18005 18028 18155 18171 18192 18236 18243 18340 18366 18428 18581 18640 18764 18935 19002 19069 19203 19561 19582 19779 19884 19974 20072 20338 20595 20629 20637 21003 21355 21406 21594 21600 21940 22287 22868 22967 23123 23130 23397 23441 23491 23563 23582 23646 23681 23723 23737 23932 24192 24255 24542 24568 24571 24618 24837 24859 24955 24964 25168 25279 25339 25538 25584 25595 25692 25717 25889 26144 26335 26579 26704 26707 26768 27083 27105 27124 27164 27199 27220 27403 27475 27608 27642 27758 27858 27863 27943 28009 28069 28076 28141 28245 28258 28311 28500 28609 28668 28767 28858 29199 29238 29349 29882 30041 30127 30131 30177 30219 30278 30378 30503 30507 30527 30691 30703 30707 30762 30783 30836 30906 30929 30958 30968 30994 31027 31032 31037 31068 31258 31494 31532 31547 31571 31689 31698 31796 31813 31970 32282 32288 32345 32422 32438 34131 34135 34516 34717 35166 35223 35502 35733 35790 35839 35954 36015 36019 36506 36562 36816 36854 38260 38746 38757 38836 39356 39377 39516 39543 39877 40046 40101 40255 40276 40687 42837 42981 42997 43677 43863 43892 44006 44212 44260 44323 44410 44486 44573 44727 44740 44761 44871 44887 44956 45042 47030 47052 47959 47985 48050 48383 48402 48583 48658 48773 48785 48862 48980 491143.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/156/213?format=asciiOpticaldefaultJ/AJ/156/213/table12Interesting targets for astrometric detectionrecnoRecord number assigned by the VizieR team.
