cds-question@unistra.frvariable-starsradial-velocityWe investigate the nature of the long-period radial velocity variations in {alpha} Tau first reported over 20 years ago. We analyzed precise stellar radial velocity measurements for {alpha} Tau spanning over 30 years. An examination of the H{alpha} and CaII {lambda}8662 spectral lines, and Hipparcos photometry was also done to help discern the nature of the long-period radial velocity variations.2015A&A...580A..31Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/580/A31CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/580/A31https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/580/A31http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/580/A31https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/580/A31https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/580/A31http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/580/A31GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/580/A31/RVRV measurements (tables 3--9)recnoRecord number assigned by the VizieR team.
