cds-question@unistra.frspectroscopic-binary-starsradial-velocityvisible-astronomynarrow-band-photometryWide-band photometryspectroscopyThe metal-poor post-asymptotic giant branch (AGB) star HD 46703 is shown to be a single-line spectroscopic binary with a period of 600-days, a high velocity of -94km/s, and an orbital eccentricity of 0.3. Light-curve studies show that it also pulsates with a period of 29-days. High-resolution, high signal-to-noise spectra were used for a new abundance study.2008AJ....136.1557Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/136/1557CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/136/1557https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/136/1557http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/136/1557https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/136/1557https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/136/1557http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/136/1557GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap3.2864930669913924e-19 6.123250280965187e-19OpticaldefaultJ/AJ/136/1557/table1List of radial velocity observations of HD 46703recnoRecord number assigned by the VizieR team.
