The Formation Rate of Blue Stragglers in 47 Tucanae
Abstract
We investigate the effects of changes in the blue straggler formation rate in globular clusters on the blue straggler distribution in the color-magnitude diagram. We find that the blue straggler distribution is highly sensitive to the past formation rate. Comparison of our models to new UBV observations of a region close to the core of 47 Tucanae suggests that this cluster may have stopped forming blue stragglers several Gyr ago. This cessation …
