The extended main-sequence turnoff clusters of the large magellanic cloud - Missing links in globular cluster evolution
Recent observations of intermediate-age (1-3Gyr) massive star clusters in the Large Magellanic Cloud have revealed that the majority possess bifurcated or extended main-sequence turnoff (EMSTO) morphologies. This effect can be understood to arise from subsequent star formation among the stellar population with age differences between constituent stars amounting to 50-300Myr. Age spreads of this order are similarly invoked to explain the light-element abundance variations witnessed in ancient...[Show more]
