Steps Towards Solving the Enigma of Multiple Populations in Star Clusters
Star clusters used to be considered to consist of stars that all formed simultaneously and with the same elemental abundances. The surprising discovery that these clusters contain multiple populations with characteristic abundance inhomogeneities remains an enigma. I will investigate whether rotational mixing is a plausible culprit, using massive emission-line stars as tracers of rapid rotation. Also, I will assess the validity of certain light elements as signatures of multiple populations.
