| Abstract: |
We present a population synthesis study of the cooling sequence of the
globular cluster 47 Tucanae. We study the distribution of effective
temperatures, the morphology of the color-magnitude diagram, and the
magnitude and color distributions. We find that our simulations are
in very good agreement with the observational data, once all the
observational biases are taken into account. Our study also rules out
previous claims that there are still missing physics in the white
dwarf cooling models at moderately high effective temperatures. We
also fit the age of the cluster using the termination of the cooling
sequence, finding an age consistent with that determined using the
main-sequence turn-off. Finally, we also investigate the star
formation history of the cluster, finding that is compatible with that
obtained using main sequence stars. |
