cds-question@unistra.frvariable-starsspectroscopyradial-velocityWe have carried out a detailed identification of lines in the optical spectrum of the post-AGB star V510Pup associated with the infrared source IRAS08005-2356. Absorbtion lines of the ions FeII, TiII, CrII, YII are presented at wavelengths from 4549 to 8546 A. The absorptions YII and other s-process elements are anomalously strong. There is also strong in the circumstellar C_2_ Swan bands. The profiles of most of the lines (of hydrogen and metals) display absorption-emission P Cyg type profiles. All the absorption lines are shifted toward shorter wavelengths, suggesting an outflow of stellar material. The expansion velocity of the envelope derived from the Swan bands arising there is Vexp=42km/s. The highest wind velocity determined from the absorptional wings of FeII(42) P Cygni profiles reachs 240km/s. Based on the star's kinematic characteristics and the amount of interstellar absorption, the distance to this object is d~3-4kpc.2004AZh....81..333Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/81/333CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/81/333https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/81/333http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/81/333https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/81/333https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/81/333http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/81/333GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AZh/81/333/table1Spectral feature of V510 Pup and the residual intensity and radial velocity derived from various featuresrecnoRecord number assigned by the VizieR team.
