J/A+A/291/121       Study of star V9 in 47 Tuc   (Storm+ 1994)

Description:
    We 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.
