cds-question@unistra.frvariable-starsRR Lyrae stars in the Milky Way are good tracers to study the kinematic behaviour and spatial distribution of older stellar populations. A recently established well documented sample of 217 RR Lyr stars with V<12.5mag, for which accurate distances and radial velocities as well as proper motions from the Hipparcos and Tycho-2 catalogues are available, has been used to reinvestigate these structural parameters. The kinematic parameters allowed to calculate the orbits of the stars. Nearly 1/3 of the stars of our sample have orbits staying near the Milky Way plane.2005A&A...442..229Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/442/229CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/259 : The Tycho-2 Catalogue (Hog+ 2000)J/A+A/442/381 : Precise positions of RR Lyrae with Vmax>12.5 (Maintz, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/442/229https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/442/229http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/442/229https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/442/229https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/442/229http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/442/229GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/442/229/table1 (Positions, velocities (given in the Galactic euclidic system XYZUVW and {Theta}, {Phi}) and orbital data (Ra, Rp, zmax, normalised z-extent, and eccentricity) of the stars of our sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/442/229/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/442/229/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/442/229/table1?GETtext/xml+votable180.050000true5.929543929.40100610.0055555555555555566/110 572 1663 2058 2089 2238 2484 2629 4219 4286 4479 4762 4833 4942 5182 5708 6301 6567 6744 7174 7518 8294 8466 8773 9027 9138 9172 9363 9429 9438 9509 9769 9938 10169 10328 10362 10541 10584 10602 10638 10862 10898 10985 11098 11123 11492 11961 12463 12512 12632 12743 12773 13066 13171 13205 13680 14373 14857 14874 14994 15106 15220 15714 16018 16022 16126 16342 16553 16602 16849 16867 16923 17158 17328 18080 18177 18502 18964 19104 19110 19169 19333 20020 20097 20267 20303 20497 21127 21146 21182 21533 21961 22111 22338 24772 24866 25199 25491 25611 25768 25803 25953 26079 26131 26170 26281 26288 26413 26435 26487 26515 26733 26756 26981 27125 27333 27824 27833 27998 28030 28143 28155 28227 28256 28383 28582 28674 28701 28813 30019 30055 30923 31054 31335 31390 31456 31648 31743 31866 32254 32636 32663 33197 33342 33465 33996 34229 34236 34240 34537 34944 35151 35423 35611 35686 35724 35852 36048 36363 36535 36605 36704 36781 37911 38087 38304 38809 38942 39152 39475 40651 40767 40806 40882 40988 40998 41022 41191 41260 41318 41991 42053 42260 42672 43405 43491 43794 44326 44498 45086 45152 45164 45337 45676 45741 45796 45992 46069 46130 46373 46650 47273 47327 47342 47527 47618 47674 47776 47821 48113 48228 48290 48459 48911 48916https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/442/229?format=asciiOpticaldefaultJ/A+A/442/229/table1Positions, velocities (given in the Galactic euclidic system XYZUVW and {Theta}, {Phi}) and orbital data (Ra, Rp, zmax, normalised z-extent, and eccentricity) of the stars of our samplerecnoRecord number assigned by the VizieR team.
