cds-question@unistra.frstellar-massesstellar-agesgiant-starsk-starsThe determination of accurate stellar parameters of giant stars is essential for our understanding of such stars in general and as exoplanet host stars in particular. Precise stellar masses are vital for determining the lower mass limit of potential substellar companions with the radial velocity method. Our goal is to determine stellar parameters, including mass, radius, age, surface gravity, effective temperature and luminosity, for the sample of giants observed by the Lick planet search. Furthermore, we want to derive the probability of these stars being on the horizontal branch (HB) or red giant branch (RGB), respectively. We compare spectroscopic, photometric and astrometric observables to grids of stellar evolutionary models using Bayesian inference. We provide tables of stellar parameters, probabilities for the current post-main sequence evolutionary stage, and probability density functions for 372 giants from the Lick planet search. We find that 81% of the stars in our sample are more probably on the HB. In particular, this is the case for 15 of the 16 planet host stars in the sample. We tested the reliability of our methodology by comparing our stellar parameters to literature values and find very good agreement. Furthermore, we created a small test sample of 26 giants with available asteroseismic masses and evolutionary stages and compared these to our estimates. The mean difference of the stellar masses for the 24 stars with the same evolutionary stages by both methods is only {Delta}M=0.01+/-0.20M_{sun}_. We do not find any evidence for large systematic differences between our results and estimates of stellar parameters based on other methods. In particular we find no significant systematic offset between stellar masses provided by asteroseismology to our Bayesian estimates based on evolutionary models.2018A&A...616A..33Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/616/A33CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/475/1003 : Stellar parameters of G and K giant stars (Hekker+, 2007)J/A+A/574/A116 : G and K giant stars stellar parameters (Reffert+, 2015)J/A+A/595/A55 : Radial velocity data of HD 59686 A (Ortiz+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/616/A33https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/616/A33http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/616/A33https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/616/A33https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/616/A33http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/616/A33GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/616/A33/giants (List of derived stellar parameters for 372 giant stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/616/A33/giants?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/616/A33/giants?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/616/A33/giants?GETtext/xml+votable180.050000true1.174918167.16644470.0055555555555555566/31 128 341 346 428 469 490 647 737 844 846 943 975 1082 1143 1249 1360 1444 1622 1696 1770 1776 2089 2150 2209 2525 2598 2619 2834 2837 2958 2973 3026 3053 3077 3087 3105 3258 3755 4123 4146 4150 4167 4358 4408 4574 4578 4690 4711 4741 4801 4846 4923 4969 5059 5073 5164 5245 5535 5564 5587 5666 5676 5694 5776 5953 5983 5997 6039 6166 6196 6219 6298 6334 6361 6493 6510 6672 6740 7040 7122 7177 7343 7402 7435 8198 8278 8333 8372 8441 8470 8498 8689 8767 8773 8834 8844 9083 9127 9213 9520 9572 9610 10084 10451 10632 10834 10886 10997 11357 11370 11394 11473 11547 11618 12516 12544 12911 12927 12953 13018 13211 13231 13282 13332-13333 13355 13443 13550 13709 13734 13801 13895 14005 14084 14233 14259 14359 14373 14557 14705 14767 14834 15106 15203 15226 15364 15410 15426 15597 15621 15628 15715 15719 16691 16834 16936 16955 16995 17000 17061 17190 17266 17303 17391 17394 17551 17568 17608 17676 17723 17811 17941 17959 18102 18166 18204 18276 18315 18471 18478 18591 18634 18659 18679 18688 18729 18871 18893 18911 18944 19047 19157 19263 19414 19672 19797 19825 19921 20027 20308 20460 20886 20893 20981 21050 21174 21324 21423 21469 21542 21605 21612 21756 21768 21806 21885 21940 21973 22015 22135 22168 22249 22304 22412 22420 22450 22518 22658 22710 22752 22798 22964 23048 23243 23278 23341 23525 23538 23540 23547 23562 23576 23579 23705 23822 23831-23832 24262 24339 24464 24799 25246 25278 25304 25608 25617 25706 25741 25816 25830 26172 26432 26552 26595 26633 26688 26959 26990 27088 27169 27198 27432 27444 27555 27604 27752 27823 27962 27979 28044 28077 28106 28436 28487 28634 28782 28968 28972 29020 29024 29359 29521 29533 29589 29657 29682 29800 30225 30228 30339 30344 30398 30518 30544 30699 30708 30732 30855 30953 31187 31297 31444 31488 31576 31784 31842 31906 32140 32182 32257 32437 32477 32575 32685 32708 32725 32732 32754 34666 34777 36414 36433 36498 36689 36759 39864 39879 40095 40336 40408 40588 40617 40757 40795 40959 44015 44191 44240 44270 44364 44372 44424 44469 44471 44485 44554 44569 44799 44859 44867 48051 48330 48519 48545 48572 48576 48886 48992 49109https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/616/A33?format=asciidefaultJ/A+A/616/A33/giantsList of derived stellar parameters for 372 giant starsrecnoRecord number assigned by the VizieR team.
