Animation of Blue Stragglers

This animation (artist’s impression) shows the movement of blue stragglers in a star cluster over time. Blue straggler stars are blue, bright stars, with a higher mass than the average for a cluster, and they are expected to sink towards the centre of a star cluster over time. Those closest to the cluster core are the first to migrate inwards, with more distant blue stragglers progressively moving inwards over time.
