A deep luminosity function for 47 Tucanae.
Abstract
CCD photometry in B and V reaching B(lim) ≅ 25 has been employed to obtain the luminosity function and color-magnitude diagram for the main sequence of 47 Tuc. For 5 < Mv < 10 the authors find that its LF is essentially flat (Δlog n/Δm ≡ 0). The CMD is successfully matched by isochrones with [Fe/H] = -0.5 and t ≅ 15×109y.
