A new color-magnitude diagram for 47 Tucanae: a statistical analysis.

BERGBUSCH P.A. and STETSON P.B.

Abstract (from CDS):

We present a statistical analysis of color-magnitude diagrams of 47 Tuc derived from original and archival BVI photometry that produces the most probable locus for single stars. After adopting E(B-V) = 0.04, we derive an apparent distance modulus (m - M)V= 13.375 and achieve good matches to the most probable locus in the [B - V, V], [V - I, I], and [B - I, I] planes with 12 Gyr, [α/Fe] = +0.3, [Fe/H] = -0.83 isochrones from the Victoria-Regina models. This metallicity is generally lower than recent spectroscopically derived estimates for the cluster, but it is reinforced by the main-sequence match with a sample of subdwarfs.
