cds-question@unistra.frhorizontal-branch-starsspectroscopyvisible-astronomytrigonometric-parallaxradial-velocityeffective-temperaturechemical-abundancesstellar-distanceA metallicity, chemical composition, and kinematic survey has been conducted for a sample of 340 candidate field red horizontal-branch (RHB) stars. Spectra with high resolution and high signal-to-noise ratio were gathered with the McDonald Observatory 2.7 m Tull and the Hobby-Eberly Telescope echelle spectrographs, and were used to determine effective temperatures, surface gravities, microturbulent velocities, [Fe/H] metallicities, and abundance ratios [X/Fe] for seven {alpha} and Fe-group species. The derived temperatures and gravities confirm that at least half of the candidates are true RHB stars, with (average) parameters T_eff_~5000 K and log g~2.5. From the {alpha} abundances alone, the thin and thick Galactic populations are apparent in our sample. Space motions for 90% of the program stars were computed from Hipparcos and Gaia parallaxes and proper motions. Correlations between chemical compositions and Galactic kinematics clearly indicate the existence of both thin-disk and thick-disk RHB stars.2018AJ....155..240Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/155/240CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/337 : Gaia DR1 (Gaia Collaboration, 2016)J/MNRAS/371/703 : MILES library of empirical spectra (Sanchez-Blazquez+, 2006)J/AJ/140/500 : Kimematics of horizontal-branch stars from SDDSS-DR7J/AJ/140/1694 : Abundances of non-variable red and blue HB stars (For+, 2010)J/MNRAS/411/435 : Stellar parameters and extinction (Bailer-Jones, 2011)J/PASJ/63/1035 : Stellar parameters and abundances of 99 giants (Wang+, 2011)J/ApJ/751/130 : SDSS-DR7 red HB stars spectroscopic data (Shi+, 2012)J/A+A/574/A50 : Chemical abundances of giants and subgiants (Jofre+, 2015)J/MNRAS/463/580 : Abundances of red giants in NGC6940 (Bocek+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/155/240https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/155/240http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/155/240https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/155/240https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/155/240http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/155/240GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/155/240/table1 (Basic program star data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/155/240/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/155/240/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/155/240/table1?GETtext/xml+votable180.050000true0.805517.552266670.0055555555555555566/125 405 453 596 597 771 776 819 1131 1218 1303 1603 1604 2217 2440 2468 2739 2817 2970 3105 3159 3257 3271 3331 3338 3599 4181 4267 4324 4371 4526 4555 4737 4869 4969 5004 5026 5056 5059 5073 5278 5311 5322 5346 5388 5438 5442 5465 5470 5488 5557 5607 5689 5700 5741 6095 6201 6466 6780 6825 6898 6967 8219 8269 8372 8472 8498 8518 8685 8721 8821 8948 9029 9083 9087 9123 9177 9192 9413 9448 9650 9843 9851 9956 10247 10266 10334 10366 10376 10379 10380 10383 10389 10391 10401 10404 10430 10434 10441 10444 10447 10456 10460 10475 10480 10495 10499 10502 10504 10505 10515 10520 10534 10544 10548 10554 10631 10632 10637 10639 10662 10664 10666 10754 10762 10795 10800 10830 10840 10861 10929 10951 10968 10987 10997 11020 11065 11100 11184 11356 11372 11441 11547 12390 12515 12583 12588 12694 12735 12827 12835 12942 13030 13043 13114 13142 13243 13296 13807 13850 14100 14215 14219 14222 14245 14246 14249 14252 14253 14256 14425 14505 14631 14701 14721 14727 14736 14744 14762 14870 14943 15012 15203 15260 15465 15503 15509 15511 15533 15597 17010 17303 17307 17312 17373 17394 17538 17578 17582 17671 17676 17823 17854 17916 18167 18186 18208 18210 18604 18609 18841 18861 19086 19136 19199 19237 19415 19485 19548 19595 19672 19703 19821 19850 19924 20040 20081 20137 20177 20208 20209 20254 20279 20308 20921 20973 21249 21690 21836 22264 22293 22356 22360 22423 22504 22833 22935 22985 22988 23048 23096 23131 23448 23695 23705 23735 23906 24013 24157 24215 24249 24333 24336 24347 24374 24420 25051 25080 25200 25324 25461 25527 25583 25706 25735 26246 26276 26381 26440 26538 26583 27234 27384 27509 27513 27586 27604 28058 28083 28103 28202 28350 28444 28463 28503 28517 28528 28671 30344 30518 30568 32091 32236 32368 32599 32685 32721 32732 36175 36518 36689 36692 36727 36855 40214 40246 40355 40749 44025 44364 44495 44507 44518 44867 45050 48553 49060 49142https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/155/240?format=asciiOpticaldefaultJ/AJ/155/240/table1Basic program star dataSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
