cds-question@unistra.frvariable-starsinfrared-photometryradial-velocityWe present an infrared K-band light curve and a radial velocity curve for the RR Lyrae star V9 in the metal rich globular cluster 47 Tucanae ([Fe/H]=-0.71). Combining these new data with the optical photometry presented in Carney et al. (1993PASP..105..294C), we perform a Baade-Wesselink analysis and derive a distance modulus of 47 Tuc of 13.23mag+/-0.17 and absolute mean magnitudes of <M_V_>=0.32mag and <M_K_>=-0.57mag for V9. We also present a well populated visual-infrared color-magnitude diagram of the cluster, reaching from the upper red giant branch to the subgiant branch.1994A&A...291..121Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/291/121CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/291/121https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/291/121http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/291/121https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/291/121https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/291/121http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/291/121GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/A+A/291/121/table1K magnitudes for V9recnoRecord number assigned by the VizieR team.
