cds-question@unistra.frearly-type-starsWe estimate the distribution of ejection velocities for the known population of high Galactic latitude runaway stars. The initial sample is a collection of 174 early-type stars selected from the literature. The stars are first classified according to their evolutionary status in order to obtain a homogeneous sample of 96 genuine main-sequence stars. Their present velocities and flight times are then estimated using proper motion data from various astrometric catalogues (including Tycho-2, UCAC2 and USNO-B) and the ejection velocities are computed by tracing their orbits back in time, based on a Galactic potential. The potential used is constructed from a mass density model chosen to fit the most recent observational constraints.2011MNRAS.411.2596Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/411/2596CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/331/949 : Wolf-Rayet and O-star runaways kinematics (Moffat+ 1998)J/A+A/402/801 : Runaway carbon stars of Blanco+McCarthy field 37 (Loup+ 2003)J/MNRAS/410/190 : Young runaway stars within 3kpc (Tetzlaff+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/411/2596https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/411/2596http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/411/2596https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/411/2596https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/411/2596http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/411/2596GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/411/2596/sample (Input data and computed values for runaway stars of groups A and B)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/411/2596/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/411/2596/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/411/2596/sample?GETtext/xml+votable180.050000true294.6906742-67.61904220.0055555555555555566/128 2056 4927 5281 5512 7240 7261 7728 8607 8794 9180 9256 9954 10158 10791 16088 16868 16948 16958 17067 17312 17321 17373 17787 18439 18486 18498 18560 18903 18928 19130 19140 19350 19392 19475 20259 20729 21158 24921 25988 26584 26666 26688 26929 27095 27300 27751 27844 28164 28244 28421 28445 28633 30925 33263 33553 33652 33808 33812 33860 34076 34118 34823 34878 35517 35544 36045 36231 36452 36857 37003 38746 40410 40432 44323 44348 44974 45229 45638 45645 45672 45984 45994 46124 47017 47068 47374 47536 47541 48077 48199 48289 48584 48640 48663 48817https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/411/2596?format=asciiOpticaldefaultJ/MNRAS/411/2596/sampleInput data and computed values for runaway stars of groups A and Br_RVReference for RV, in refs.dat filemeta.ref;pos.frameintrecnoRecord number assigned by the VizieR team.
