cds-question@unistra.frsurveysmilky-way-galaxyradial-velocityeffective-temperaturemetallicitystellar-radiistellar-distancestellar-agesCombining stellar atmospheric parameters, such as effective temperature, surface gravity, and metallicity, with barycentric radial velocity data provides insight into the chemo-dynamics of the Milky Way and our local Galactic environment. We analyse 3075 stars with spectroscopic data from the Sloan Digital Sky Survey III MARVELS radial velocity survey and present atmospheric parameters for 2343 dwarf stars using the spectral indices method, a modified version of the equivalent width method. We present barycentric radial velocities for a sample of 2610 stars with a median uncertainty of 0.3km/s. We determine stellar ages using two independent methods and calculate ages for 2335 stars with a maximum-likelihood isochronal age-dating method and for 2194 stars with a Bayesian age-dating method. Using previously published parallax data, we compute Galactic orbits and space velocities for 2504 stars to explore stellar populations based on kinematic and age parameters. This study combines good ages and exquisite velocities to explore local chemo-kinematics of the Milky Way, which complements many of the recent studies of giant stars with the APOGEE survey, and we find our results to be in agreement with current chemo-dynamical models of the Milky Way. Particularly, we find from our metallicity distributions and velocity-age relations of a kinematically defined thin disc that the metal-rich end has stars of all ages, even after we clean the sample of highly eccentric stars, suggesting that radial migration plays a key role in the metallicity scatter of the thin disc. All stellar parameters and kinematic data derived in this work are catalogued and published online in machine-readable form.2018MNRAS.481.3244Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/481/3244CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)IX/49 : XXL Survey: First results (Pierre+, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/481/3244https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/481/3244http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/481/3244https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/481/3244https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/481/3244http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/481/3244GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/481/3244/marvels (MARVELS catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/481/3244/marvels?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/481/3244/marvels?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/481/3244/marvels?GETtext/xml+votable180.050000true164.1905739.811890.0055555555555555565/107 764-765 779 945 969 1107 1195 1380 1429 1537 1600 1659 1666 1688 1699 1705 1782 1808 1810 1936 2338 2359 2389 2393 2578 2580 2682 2771 2774 3425 3644 3646 3688 3691 3693-3694 3739 3741-3743 3760 3765 3780 3782 3786-3787 3792 3865 4976 5007 5030 5084 5086 5563 5579-5580 5601 5920 6056 6528 6563 6742-6743 6904 6993 7018 7137 7692 8172 6/423 425 427 440 442 772-773 784 3047 3053 3064-3065 3068 3110-3111 3113 3115 3122 3128 3205 3691 3694-3695 3706 3777-3779 3792 3851 3853-3855 3866 3873 3875 3888 4422-4423 4434 4440 4442 4779 5034 5371 5374-5375 5509 5511 5517-5519 5528-5530 5713-5715 5720-5721 5724 6145 6147 6160 6162 6231 6404 6406 6408-6409 6412 6635 6648 6650 6659 6662-6663 6668-6670 6689 6711 6716-6717 6719 6760-6762 6795 6808 6810 6817 6832 6976-6977 6979-6982 6992 7111 7117-7119 7122-7123 7126 7132 7141 7152 7197 7199 7236 7238 7244 7402-7403 7701-7703 7708-7709 8954-8955 8958-8959 9356 9358-9359 9376-9377 9379-9381 9429-9431 9433 9435 9551 9553 9555 9561-9566 9571 9577 9580-9582 9584 9602 9608 9610 10269 10271 10293 10309 10316 10318 10324-10326 10329 10336-10338 10340 10685-10687 11028-11029 11031 11072 11090 11108-11109 11120 13614-13615 13626 13697 13699 13705 13708-13709 13712 13714 14559 14567 14573 14581-14583 14588-14589 14730-14731 14749-14751 14757-14760 14768 14770-14771 14780 14782 14792 14794-14795 14816 14826-14827 14830-14831 14954-14955 14962-14963 15018-15019 15044-15045 15056-15057 15059 15109 15111 15124 15126-15127 15132-15134 15139 15141-15143 15154 15160 15172 15174 15232 15437-15439 15448 15450 15457 15459 15472 19818-19819 19861 19863 19869 19908 19912-19913 20022-20023 20066-20067 20072-20074 20117 20124 20126-20127 20144-20145 20147-20150 20160 20327 20333 20340 20342 20348 22243 22246-22247 22249 22251 22286-22287 22298 22309-22311 22313 22315 22328 22401 22403 23594-23595 23598 23684-23686 23689 24203 24206 24228-24230 24232-24233 24236-24237 25431 26116 26118 26120-26121 26124 26126 26264 26266-26267 26276-26277 26279 26288 26290 26606-26607 26962-26963 26966 26993 26996 27551 27572-27573 27575 27592 27594-27595 27624 27893 27895 27900-27901 27903 27969 27971 27980-27981 27984 27986 28064 28066-28067 28459 28462-28463 28544-28545 28547 28556 30746-30747 30757 30759 30765 30774 30776-30777 30780 32653-32655 32664 32666-32667 32676-32677 32679 32766-32767https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/481/3244?format=asciidefaultJ/MNRAS/481/3244/marvelsMARVELS catalogue2MASS2MASS survey IDmeta.idcharrecnoRecord number assigned by the VizieR team.
