Description

Nearly all the star clusters with ages of ∼1-2 Gyr in both Magellanic Clouds exhibit an extended main-sequence turn off (eMSTO) whose origin is under debate. The main scenarios suggest that the eMSTO could be either due to multiple generations of stars with different ages or to coeval stellar populations with different rotation rates. In this paper we use Hubble-Space-Telescope images to investigate the ∼80-Myr old cluster NGC 1755 in the LMC. We find that the MS is split with the blue and...[Show more]
