  • As with most data analysis methods, the Bayesian method must be handled with care. We show that its application to determine stellar evolution parameters within globular clusters can lead to paradoxical results if used without the necessary precautions. This is a cautionary tale on the use of statistical tools for big data analysis.

  • Some star clusters in the Large Magellanic Cloud have extended main-sequence turnoffs, suggesting that the component stars have different ages. However, if the blue main-sequence stars were initially spinning rapidly, and experienced braking, the apparent age difference disappears.

  • The observed range of luminosities of the extremely hot ‘blue hook’ stars of the globular cluster ω Centauri is successfully explained by a model in which the progenitors of these stars are second-generation helium-rich stars characterized by a range of rotation rates arising during the cluster’s very early evolution.
